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.
2021 Android and newer
- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR 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#.

Generally when I visit USA, I purchase T-Mobile sim after landing in USA which has a plan for unlimited India and US calls and data.
This is the first time I used TSIM, and I was amazed by it’s service and responses. I got TSIM delivered on next day and was activated on the day I requested. The sim was of Lycamobile but it was using T-Mobile network and I got 5G speed most of the time. Purchasing TSIM was way cheaper comparing to purchase it in US.
Do check your mobile compatibility by providing your IMEI number before ordering. If your mobile is not compatible, then you will face issue. It is not TSIM issue but this is how US mobile network works.
Services Tsim –
Thank you for your kind and detailed review.

I have been using TSIM product for my USA visits for the last many years. Courier delivery at home is prompt, it gets activated on the day mentioned, pricing is very economical and connectivity has never been a problem
Simriti –
Excellent connectivity. Good data speeds. Without a doubt the best SIM in all major US cities. Haven’t used it in under populated areas.
Teji –
Used the SIM in Chicago. Worked very well. Never let me down. Data speed excellent. Network coverage also very good all over the city…even the subway! Very satisfied!
Services Tsim –
Your phone V11 Pro is not fully compatible with the network due to frequency mismatch. We encourage our customers to provide their IMEI numbers in the provided text box while ordering so that we are able to do a compatibility check. We are sorry you had such a poor experience with our product, but thank you for taking the time to write a review.
Services Tsim –
Thank you for your kind review.
Rajesh Kulkarni –
This SIM was highly recommended but it failed to deliver. Connectivity was very bad in California (barely some data connectivity in some pockets) and absolutely no data connectivity in Austin, Texas. I had a harrowing time relying on this network at the airport when I had to fill up a form and there was no data connectivity.
I would not recommend this service.
Services Tsim –
Thank you for your kind review.
Kamlesh K –
Tried US Sim. Good network. Value for money. Very satisfied.
Ashish –
Data did not work in Michigan. Very poor Signal.
Services Tsim –
Samsung Galaxy M20 is not compatible with the network you chose. Many phones sold in India do not roam fully outside of India due to which we request customers to provide the IMEI number that lets us check compatibility of the phone. We regret the inconvenience you faced.
Services Tsim –
Thank you for your kind words and continued support.

I am a repeat customer of TSIM. I never faced any issues, and the network has been consistent (I guess they partnered with multiple network providers in the US). I happened to reach out to their customer care from the US when there was an issue, and it was resolved promptly.
Overall best customer service and value for money
Services Tsim –
Thank you for your kind words and detailed feedback.

Eliza Abraham –
The process was easy and simple. Got my SIM card within a day. Activated on the mentioned day. Very prompt support & customer service. The coverage was very good in NJ, NC (even few remote areas). Totally worth the cost.
Suggestion: A way to get detailed billing of usage.
Harsh Vardhan Joshi –
Easy to get SIM great support team.Only thing they should do is have variable days offered. Like I will be in USA for 34 days and was without active sim for 5 days 🙁
Services Tsim –
Thank you for your kind words and suggestion. We will try to issue a daily SIM card too.
Services Tsim –
Thank you for your kind words and review. We will forward your suggestion to our partners.
Services Tsim –
Acting on your suggestion we have released an AT&T daily eSIM option that is suitable for situations like these. Thank you.
Nitin Shah –
This is the third trip, I’m using this SIM.
It is very useful and the coverage is good.
I have recommended this to a lot of others.
Services Tsim –
Thank you for your kind review and recommendation.
Girish Garg –
Excellent Product. I have been using this SIM in USA for the last one month. The SIM activated on time and the moment I landed in USA and switched-on my phone ( with the TSIM inserted), the SIM was active and I could connect with my friend waiting outside the airport. There has been absolutely no problem in either local calls or calls to India. The data speed is good. It is a Lycamobile connection and when I wanted tk extend the validity of my SIM, I cud easily do it online. It is cheaper than taking a SIM from USA. For eg, the same one month validity plan from Lycamobile is USD 29 ( whereas it is Rs 1499 by TSIM). This is my genuine personal feedback and not a paid review of any form.
Joshua –
The sims worked well
The service support was excellent when there was an issue
On the last day before expiry calls did not go through kindly check this
Overall a good product and would use again
Services Tsim –
Thank you for your kind review. We will certainly check why the calls did not work on last day.

Usually reliable and works well. Some minor issues like SMS not being able to send to INDIA exist. Otherwise it is fine
Services Tsim –
Thank you for your kind review. We will investigate why SMS to India did not work for you.
Kulvinder Singh Monga –
I bought a US sim ,1 mth / 7 GB plan. It was incredibly easy to use. I got the signals while my flight touched down & call connected immediately. No issues with data usage. Only I couldn’t track my data balance. Would strongly recommend.

Tsim is a convenient and reliable way to remain connected when you land into a foreign land. The team is prompt in delivering the SIM card and the follow up communication of the mobile no is also efficient. I swear by tsim and use their services whenever I travel abroad. Keep it up!
