American lawmakers would like to pass laws forcing carriers to identify buyers of "burner" prepaid services but these laws haven't passed yet. Additionally I reached out to the company asking about their customer data protection rules and how/when they turn over data to law enforcement but I have not received a response yet. Will update this post when a response is received.
The technical stuff
Like RoamMobility, the ZipSIM service runs on-top of the T-Mobile network. The network has dramatically improved over the last 2 years and call drops and slow data are things of the past. I have tested T-Mobile service (in the last 3 months) in Los Angeles, Silicon Valley, San Francisco, Chicago) and service has been exceptional.
Additionally you need an unlocked smartphone to use ZipSim (or any other carrier's SIM) but your phone's should always be unlocked. Most carriers will do it for customers in good standing for a nominal fee.
Comparing ZipSIM and RoamMobility
How does the little brother compare to its older sibling? ZipSim is more expensive for less data:
- ZIPSIM - A 7 day ZipSim card costs $US25 and includes 500MB of data, unlimited US talk, unlimited global text & voicemail
- RoamMobility - A similar 7 day plan costs $CAD34.65 (~$US26) and comes with unlimited US/Canada talk, unlimited global text, voicemail, 3.5GB of LTE data.
There is one other important distinction. With RoamMobility, if you consume all of your allotted LTE data, you continue to get unlimited data at 2G speeds while on ZipSim you are cut-off. 2G isn't great but it is fast enough to send emails, text messages and use asymmetric instant messaging (Whatsapp, Facebook Messenger, etc).

Conclusion
If you are an EDC prepper, this is a good solution to keep a secondary, instant activation, no registration SIM card ready.
If you are an infrequent traveler to the USA and have modest data requirements, this is definitely and easy solution.
If you have spontaneous last minute travel to the US, this is a good solution.
If you don't need the privacy of ZipSim and have planned trips to the USA, I still believe RoamMobility is the best option. Better pricing and more flexibility. As I write this, they have a promo on their SIM cards and offer international shipping.
