- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.

Not quite as satisfied with this card, this time, as I have been with TSIM Europe cards. For one thing, TSIM told me I would need another handset – but I have only one, so I took my chances. I wanted to be able to use Google Maps for some driving I was going to do in California. If I got the route while in Wifi range, then it worked fine while driving. But if not … actually getting the route on mobile data was too slow. I realize this is no fault of TSIM, who had warned me.
Other than that, all was ok with this card. I was able to make local calls without problems.
Many thanks.

We apologise for the inconvenience. USA operators are picky about the handset they allow on their networks. Most Chinese brands are not allowed. Also many phones sold in India do not have the frequencies required to roam everywhere in USA. Thank you for your balanced review and taking the time to record your experiences.
