eSIM Advantages

- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.

eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- 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.
- Transfer of eSIM: To transfer an eSIM from one phone to another you must visit the store of the Operator concerned. However some USA eSIMs can be transferred from one iPhone to another.

The notification is sent to the phone you intend to use on your trip for which you have given us the EID and IMEI number by dialing *#06#.

Had a hassle free experience with both the buying and activation process as well as usage in the USA. The coverage throughout the states was great. The customer care of tsim through their website chat are very prompt and understand your issue well. They even went the extra mile to help me pick a phone that was compatible with the USA frequency when I didn’t want to spend a lot on buying a new flagship iphone. I ended up buying a Realme GT 6T for 30k after ensuring that it has all the bands that T-mobile uses and it worked flawlessly for me. Definitely recommend tsim!

I purchased Mobile SIM Card for my GOOGLE PIXEL mobile phone from TSIM for my USA Trip in September 2024 for 30 days period. IT worked absolutely fine & Activation was also very easy. Internet Data Speed was 5G & was very fast. Connectivity of Calls was also fantastic. I am fully satisfied with this mobile SIM card product of TSIM. My travel areas were California, Boston , New Hampshire , Vermont, USA. It worked properly in all these areas of USA. I also recommend it for other travelers for their USA trip.

I am back in india from USA.
I had very experience with your sim card. It was so convenient. I could use within seconds after landing.
To use Uber cars, it was must.
I prefer physical Sim Card.
I strongly recommend to buy in India. And activate 2 days before departure.

Thank you for your kind review and for pointing out a benefit of local SIM cards.

I bought this sim thinking this will be useful in Canada too as I landed in Canada and was suppose to travel to US from there. But unfortunately it did not get activated in Canada and my US trip got cancelled and had to return to India. So the Sim was of no use to me, even though I bought it well ahead of my travel.
Services Tsim –
We are sorry the eSIM did not work for you in Canada and have processed a refund. Thank you for taking the time to record your experience.

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.
Services Tsim –
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.
