Do you need a dual-SIM smartphone?

GeneralEdward Kiledjian

Do I need a dual-sim phone? The answer is probably not. Most people sign a carrier contract and live with that service for two years. 


There is a small niche group that could benefit from a dual-SIM phone, and this is an article for them. Who are these mythical "special" people:

  • users with a personal and professional mobile phone line that want to carry one phone
  • users that travel often and want to use a low-cost SIM in their destination
  • users that live in regions were carriers aren't national providers, and "good" coverage requires service from 2 providers (much of Asia)
  • users that can find low cost unlimited data-only SIM and want another SIM for voice calls and text messaging, 

Not all dual SIM phones are created equal. 

Categories of dual sim phones

Passive dual-sim phones

Passive dual-SIM phones can only use one of the SIM cards at a time which means the user can switch between SIMs using software or a physical switch. 

Standy dual sim phones

Standby dual sim phones (often with the MediaTek chipset) use both SIMs using time multiplexing. Anytime you start using one of the sims (to make a call, send a message or use data), the other SIM is ignored. If someone calls the second sim when the first one is "active", the caller would receive a busy signal.

Active dial sim phones

Active dual-sim phones are capable of using both sims simultaneously and typically have to IMEIs since the phones come equipped with two radios. 

and we continue...

Because things weren't complicated enough, there is also the concept of unequal connectors. Some phones will be passive or active dual sim but may only be able to support full speed 4G on the primary SIM while slowing down to 3G/2G for the second sim.

Some buys mistakenly assume you can leverage both SIMs simultaneously for doubly fast data connectivity. This simply isn't the case. Dual sim capable phones do not perform network bonding to allow dual network stream aggregation. 

When I upgraded my daily drive smartphone, I switched from an iPhone 6s Plus to a Note 8 dual sim. When not travelling, the second slot hosts my SD card, but when I travel, I will load my KnowRoaming SIM. 

I know several account executives that use dual sim phones (one with their personal sim and the other with their work one). This means they can carry one device yet send/receive messages from either. Even in Canada, I know people that use dual sim phones with low-cost fringe providers. They use these providers when in their home zone for cheap service but switch to a pay as you go national carrier when outside of their "home" coverage area.

My Note 8 SIM Manager

  • I can choose if both SIMs are active.
  • I can choose which service to use with which SIM by default (calls, texts, mobile data).
  • I can even ask the phone to confirm which SIM card to use before each call.

Another important consideration

With carriers that support VoLTE (Voice over LTE) or VoWIFI (Voice over WIFI), this functionality is typically only supported on the primary SIM slot. Don't expect both to support VoLTE and VoWIFI. 

Where do I buy a dual sim phone?

Most North American phone models do not come in dual sim versions. The most common way to buy a dual sim phone is either from an importer or you have to import one from a region that sells these devices.

My 128GB dual sim Note 8 was imported from Hong Kong by a Montreal based smartphone importer called PDA Plaza (this is not an ad and is not a sponsored post). I was able to buy my dual sim phone cheaper than what I would have paid locally from Samsung, Bestbuy or my carrier.

There are many options to choose from including Samsung, LG, Asus, OnePlus, etc. Just make sure you check the specifications and ensure the device supports the dual sim model you are looking for.

Examples

Asus Zenphone 5

OnePlus 5T

Huawei Mate 10 Pro

Xiamo Red Mi dual sim

Skyroam Solis Review: a traveller's best friend?

GeneralEdward Kiledjian

I've been using a Skyroam hotspot for many years now and my 2 most popular blog posts (for the old device and service) are here: 

They recently upgraded their back-end service and global WIFI hotspot, and I wanted to test and review it for you. 

Solis is the latest version of the Global WIFI hotspot sold by Skyroam. For those new to this company, they offer a small portable global WIFI hotspot that works in 100+ countries, costs $10US a day for unlimited data and is activated on demand.
 
Although I had many complaints about the pass purchase process with the original product, their hotspot has been part of my every day (EDC) carry kit for three years now.

The Solis improves on its older brother in 2 days:

  • it now supports LTE speeds on countries were it is available (otherwise it drops down to 3G) 
  • it can now operate as a backup battery (in a pinch) to charge your mobile phone

Nice little intro video

I have had the Solis for several months and have already taken it on a US road trip. It is a well-built successor to the original Skyroad hotspot, but the world has changed.

When I started using the original Skyroam in 2014, my carrier didn't offer a global travel package, and it was a pay per megabyte type affair. It got very expensive very fast. Today my carrier offers a US travel package for $7 a day or a global package (in 80+ countries for $10 a day).

If all you need is access on one device, then your carrier package may be more advantageous since it is immediate and does not require any changes. But.... The Skyroam Solis offers coverage in more countries and can provide wonderful internet goodness to up to 5 devices simultaneously. 

In my case, I still rely on Solis or KnowRoaming when I travel since I know that they will offer service everyone for one set price and it is one less worry when I travel. 

The device

If you look at the above picture, the Solis is a beautifully visible shade of orange. It is made of plastic that should withstand the rigours of travel very well. If the battery does weaken, you can order a replacement from Skyroam.

I find the Skyroam Solis much easier to carry than its competitors (including the Geefi).

Using the device

You probably noticed that the device (unlike its older brother) doesn't have a screen. To manage the device, you turn it on and connect to it from your smartphone. You will then be presented with an information page showing signal, passes left, battery level, etc. To use the device "in the field", you turn it on then press the WIFI button on the top. This automatically applies one of your day passes and you get 24 hours of internet. It knows where you are and downloads a virtual SIM for the Skyroam partner in that country. 

You can travel to as many countries as you want during that 24-hour window. All you have to do when you switch countries is turn the unit off and back on. When it starts up, it will identify the local country and download the appropriate country SIM.

You could open the a.skyroam.com captive portal from any device with a browser but it is formatted for smartphones (will look odd on a laptop). Why isn't it responsive?

The Solis is charged with any USBC adaptor which is fantastic if you have a USB C smartphone and laptop. You can charge everything with one adapter.  They provide a mini USB-C to USB-A adapter so you can charge other devices from the Solis but I wouldn't recommend it. WIFI needs every little bit of juice in that battery. 

In my testing (in zones with good LTE coverage and with 1 device connected), I was able to eek out 10-14 hours of usage on a single charge. This number will drop if the wireless signal is weak and/or if you connect multiple WIFI devices to the hotspot. When I tested it with a Chromebook and a Note 8 smartphone, I still got 10 hours of solid use (usage was primarily web pages without heavy streaming).

The software is periodically updated which is a nice touch. I recommend you start the device and let it connect to your local home network (without using a pass) before travelling. If the device needs an update, better to do it now then at a foreign airport waiting for the 15 minute upgrade process to complete. 

How fast is the connection?

I will not post speed test results because that depends on the local carrier, congestion, etc. I will say that in my testing, the Solis achieved LTE speeds comparable to an iPhone 6s Plus. The Note 8 outperformed it with is carrier aggregation technology. 

There is an LTE cap of around 500MB in a 24 hour period. After this, they throttle the connection down to 2G. They claim that this isn't automatic and done to protect the experience for all customers, but I hit this limit consistently (for testing) and saw my speed drop to dial-up performance. At the lower throttled speed, even simple apps like Google Maps took forever to load, and GPS navigation became impossible. 

I understand the need to control their costs but wish there were a way to buy more LTE access if I needed it. 

What about security?

September 2016, I reached out to Skyroam and complained about major security gaps on their online pass purchasing website. After multiple attempts to responsibly disclose the issues (with no follow-up from Skyroam), I wrote an article about it. I am happy to report that the new version of their online portal has fixes all of the issues I previously reported.

What about the general security? It is as secure as your home internet connection. My standing recommendation is to use a VPN where/when possible. You can get a VPNUnlimited lifetime VPN subscription for 5-devices for $18 (promo link), so you have no excuses.

So should I buy a Skyroam Solis?

So the question you are asking yourself is "Should I buy the Solis?". There is no simple answer. If you used the old version, then the Solis is a wonderful upgrade. Every time I tried it, it worked flawlessly without a hitch. The cost is predictable, and I have a bunch of passes purchased ready to use when needed. 

If you are a European with an EU SIM travelling within the EU, you get free roaming anyway. If you are an American with one of those great TMobile plans with free global roaming, you probably don't need this device either. 

A Skyroam PR rep had said months ago that additional functionality would be unlocked on the device (like Bluetooth and GPS), but since they are not available today, I can't factor them in as a benefit. 

For everyone that travels more than twice a year (and doesn't have free roaming), you really should consider it. The best recommendation I can make is that I own one and carry it with me every day (even when in my home country). I will be travelling considerably over the next four months (within the USA and globally) and will be using this thing a lot. 

If you travel once a year and don't want to buy a Skyroam Solis, you can rent one directly from the company. They will mail it to you or you can pick it up (US pickup is available in San Francisco, Atlanta and Austin.)

Three upcoming Alcatel handsets will have the KnowRoaming SoftSim embedded in the phones. This means users will gain access to the global KnowRoaming network (50+ countries) and benefit from reduced roaming rates.

Roam Mobility launches USA Monthly Plans

GeneralEdward Kiledjian

I've written about Roam Mobility before:

Today Roam Mobility is launching new monthly plans that include unlimited talk, text and data. It is a middle of the ground offering between their day plans and their 3-month snowbird ones.

Although these plans were originally designed for Canadian travelers heading to the USA, it is really applicable to anyone going to the US (Europe, Asia, Middle East, etc).

At launch, there are 2 monthly plans (30 day) which both include unlimited talk and text but differ in their data offering:

  • 1GB of 4G LTE for $39.95
  • 4GB of 4G LTE for $64.95

Once you consume all of your data, you get unlimited 2G data. In my testing, the TMobile LTE network is excellent but their 2G network is so so.

All you need is a non-expired Roam Mobility SIM card and then you can choose these plans on their website.

Why a Canadian should choose Roam Mobility

Telus, Rogers and Bell have all started to offer special Roaming plans ($5-7 per day) where you consume your home monthly plan when in the US. The attractiveness of this plan is the ease of use. You keep your same SIM and number. 

Most Canadians have limited data plans and the risk you run is the overage charges once you've eaten your monthly allocation. With Roam Mobility, you have to switch SIM cards but you are given ample 4G LTE and even if you do bust your cap, you get unlimited 2G connectivity. At least there won't be any $50-100 surprises at the end of the month.

What is my review of Roam Mobility

I have tested almost every conceivable USA travel solution from Roam Mobility, KnowRoaming all the way to buying local SIM cards upon landing. I have found the Roam Mobility solution to be the most robust one I have used.

KnowRoaming provides "unlimited" data for $US8 a day but it is slower 3G. Additionally during my last trip to San Francisco, I couldn't get inbound calling to work and finally gave up after 45 minutes on the phone with their support person. I didn't have my Roam SIM so I was stuck paying the Telus $7 a day fee.

So for USA only travel, I would buy a couple of Roam Mobility cards and use them.

Free unlimited video calling when you travel

GeneralEdward Kiledjian

In November, I wrote an article that explained the new free unlimited Whatsapp offer from KnowRoaming for travellers. 

TL;DR: All KnowRoaming customers get free unlimited Whatsapp text, picture and voice messaging in any of the countries KR supports.

When you consider Whatsapp is the primary communication tool for most users and that KnowRoaming has an extensive global roaming partnership network, it was a great win for their customers.

The only thing that was not free was video messaging. Video messaging was specifically excluded but this week, KnowRoaming added it to its free Whatsapp offering. So the KnowRoaming free unlimited global use offer includes all Whatsapp services:

  • Text and picture messaging
  • voice calling
  • video calling

And it is automatically available to all KnowRoaming customers. If you have KnowRoaming credit, and you should if you travel, they will refund Whatsapp usage charges every couple of hours. 

What about competitors?

I used SkyRoam many times during my global trips but stopped when I realized their account management webpage (adding credits, storing credit card information, etc) was all being transacted in a non-secure manner. Wrote about it here. Mistakes happen but the most frustrating part of the entire SkyRoam issue is that they ignored me for the longest time then promised to fix it ASAP but didn't. Obviously customer security isn't their top priority.

The SkyRoam global WIFI Hotspot should be considered un-secure and I strongly recommend travellers find other options.

I am waiting for the GeeFi to ship but until then, I will stop to KnowRoaming.

The KnowRoaming issues

KnowRoaming works very well when enabled but enabling it isn't easy and reliable. You need an unlocked phone and I have had issues where the app couldn't connect to the internet in the remote location and thus wouldn't let me enable the KnowRoaming sticker. 

Then once you activate the plan, you have to install the KnowRoaming profile which means you can't VPN when using KnowRoaming. This VPN limitation is a major problem when using public wifi. 

The third issue is related to speed. All KnowRoaming connections are 3G even if the partner network and your smartphone support LTE. I was told this is being looked at but I haven't been given any promises or dates.

Conclusion

After everything is said and done, KnowRoaming is (in my mind) the best solution for global roaming on the cheap today. I am anxious to test the new crop of global roaming hotspots that will hit the market early 2017. 

KnowRoaming really needs to spend the time and money to completely rework its app and to make the enable/disable process easier.
