Coverage
Our cheaper SIM cards work on the T mobile network, either directly or through their partners. T mobile is an ultra fast network, however its remote area coverage lags that of AT&T. If you intend to visit many remote areas in the USA, such as Alaska, natural beauty spots, national parks etc, you may want to consider our SIM cards that use the AT&T network, marked (High Coverage).
Receiving calls
People in USA can dial your number directly to reach you, for example, 1 804 555 1233; People outside USA need to add + to your number, for example, +1 804 555 1233
Calling a number in North America
Dial the 11 digit number directly; for example, call number 1 804 555 1233 directly. You can also add + to the number before dialing. There is no distinction between a landline number and a mobile number in North America
Calling India using Direct Dial
Dial “011” or “+” + country code + phone number. For example, to call India number 022 24216344, dial “01191 22 24216344” or +91 22 24216344.
Calling India using 2 stage dialing (for High Coverage cards):
Dial USA Access Number +13476701779 & when prompted dial the India number in full international format. E.g. 912224216344).

What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- 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.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
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.
Activating eSIM on your Device using a QR Code
Most eSIMs are installed using a QR code. The QR code is sent to you by eMail. You need an Internet connection to install an eSIM
iPhone XR, XS and newer
- Go to Settings, then Cellular.
- Select Add a plan, and the Camera app will open.
- Point your camera at the QR activation code until you see a message that says Installing cellular plan.

- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR code
- Scan the QR activation code
Activating eSIM on your Device using an Operator Notification
T-mobile, AT&T and some other operators make it even simpler to install eSIMs. They send a notification directly to your phone. Just tap on the notification and follow the instructions as in images below. 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#.

Awsome connectivity. Very Good internet speed. 4gb was more than enough for my 10days stay. Will recomend it for sure.
Subramanian –
Calls with in US was decent (not the best) but the call quality to India was very poor and Time lap was also there.
Network coverage is decent in US but will not suggest if majority of calls is to talk to India.
Services Tsim –
We are sorry calls to India were poor quality. We are inquiring into the specifics to find why this has happened.
Tusharkumar Bhatt –
It was a life saver for me. It has helped me a lot when I landed in US. Nice Product.
Services Tsim –
Thank you for your kind words.
manishchuri –
Excellent service by the team and had no issues with the sim used in Chicago.
Best price for unlimited calling
Vikram Agrawal –
Good service. Used in Seattle Area ([Trademark edited] SIM using T-Mobile network) without any hassle.
Opted for payment after delivery, SIM got delivered next day and got activated in 1Hr of payment. In fact, I was able to login and see all plan details on [Trademark edited] mobile website also SIM started working in India itself on Roaming immediately after activation.

2. data stopped after my high speed4g usage…low speed data is not so good
3. data provided is low
Services Tsim –
Thank you for your kind words and for specifying the countries in which it worked. Thank you also for your suggestion regarding including sim cards ejectors with our packaging.
Services Tsim –
Thank you for your kind words. We do have a SIM for unlimited 4G data for both urban coverage and high coverage options.
Utkarsh Patange –
Value for money. The SIM worked flawlessly with my Nexus 5 (North America model) in Salt Lake City, Las Vegas, Los Angeles, Anaheim and San Fransisco.
I had bought the 1 GB 4G plan valid for 1 month for my 15 day trip. I would have appreciated it if there was a 15 day alternative as I suppose most visits are not more than 15 days.
Also, it would be great if a SIM card ejector was included in the package. It is a simple thing and I’m sure it would be appreciated.
Navneet Singh –
I was initially planning to buy the T-mobile SIM but the TSIM team told me it may not work with the handsets that I was carrying and suggested the ATT (H2O) one. However, it did not work in my primary handset. Luckily it did work in the 2nd handset. Not sure if it was worth taking ATT instead of T-mobile as I was essentially in the urban areas (main cities) of California where as is known, the T-mobile coverage is better than ATT.
I would also like to explore the possibility of having a life time SIM
Services Tsim –
We apologise for the fact that the SIM card did not work with your primary hand set, but are happy that it worked with the other one. For a lifetime SIM card for USA we recommend the Lifetime Global SIM Card. Thank you for taking the time to review the product.
Sonal Goyal –
I had a lot of delay in getting the card though I paid for express shipment. The company did not provide me refund of express shipment though sim was 3 days late and I had to do multiple follow ups with the courier as well as the support team. Voice quality in US wasnt good too.
biswanath.debnath –
I purchased a 1 GB for 1 month USA phone and data SIM card and used it in Washington DC and New York City. The phone line has generally been good, although, it did not work at the airport upon arrival. It took a while for the phone line to work, after which both phone and SMS were just fine. I called and sent SMS to India, Philippines, Vietnam, and the USA successfully.
The performance of the data segment was poor. I did not get internet connectivity at all for the first two days. The TSIM staff were very helpful, they called me up a few times to fix the APN, but did not work. I found a solution after Googling for the right APN for T-Mobile and internet then started working, but reception was consistently poor and unreliable. For example, when I would order for a Lyft or Uber cab, the internet would fail and I could not order for a cab.
Overall, I recommend the TSIM’s service. The phone service is praise-worthy and price-wise economical.
Shubham Dubey –
I don’t expect too much from SIM cards like these but then I saw reviews here and got really excited and bought 2 cards, one H2O (AT&T) and one Lyca (T-mobile).
Did I like it?
For data – YES a lot, easily the best out there
For calls – absolutely awful
Details – It was mentioned that voice calls to India are free for first 10 numbers, and free 300 odd minutes for other India numbers. After initial 2-3 days, I couldn’t make any calls to India.
Don’t think I’m saying it’s not value for money, it is priced just about okay and if this calls-to-India problem is not prevalent then it is a good sim. But I couldn’t use it for calls which they said I could
Services Tsim –
We are unable to trace the cause of your inability to make calls to India due to the time that has elapsed since your trip. We apologise for the inconvenience and thank you for your understanding.
NIDHI BUCH –
Good service, instant activation on airport.
call drop and voice clarity problems some time.
Data is also not activated properly .
But for voice it is a good option for tourist.
Thanks T SIM

Hi TSim Team,
Outgoing and Data services were excellent from Houston, Tx. Incoming from India was not connecting and I raised this to your support but unfortunately till end of my trip the issue was not solved. If incoming related issue was not there then I could have rated 5 for your service.
Once again it was great experience with outgoing and data services!
Regards,
Vijay

Worth for price, network coverage is pretty good at most of the states in US. Bad part was found lot of network signal issue in Orlando, US.
Services Tsim –
