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.

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.

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.

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

Thank you for your kind words and detailed feedback.

Hi. I am using this TSIM in USA from last one month. Activated on 12 th April 2022on a 3 month’s subscription SIM. The service and coverage are absolutely FANTASTIC. The connectivity is FAST. I am happy, I made the Right choice. Only wish is that we need more data.All the best !!!
Services Tsim –
Thank you for your kind review. We are constantly increasing the data allowance in all the plans and should be able to increase it even more soon.

Thank you for your kind review.
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!

I have bought T sim on two visits to USA- it has worked perfectly every time- no issues in making calls , no internet problem. Only -I couldn’t send SMSs. Very good option for staying connected as soon as you step into USA
Services Tsim –
Thank you for your kind review and understanding. We are sorry you could not send SMS. We will check why with the operator.
Sushant –
Service is good but would like you to provide a place where the handset can be identified if it would work in the country or not.
jayantbiswas –
I have used TSIM services, both SIM cards and Insurance and have found it great value for money. The US sim works very well; last year I had used it, good network, infact even while I was in immigration line, I was getting data and calls! This time I bought the sim in mid March but due to the lockdown could not travel. But the TSIM company has promised to extend the activation date for whenever I travel next. I may not be able to travel till next year, and I would request them to extend the validity by a year on humanitarian grounds, so that my money does not go waste. Their service is very good and I always use their sims for any international travel, whether US, or Europe or other asian countries.
Services Tsim –
Thank you for your kind words.
HITESH muchhala –
My experience of your sim was very good. I have given your reference to each and every friend of mine . I had no problem at all. Thank you
Services Tsim –
Thank you for your kind words and recommendations!
drvivek.patwardhan –
Very good service.
It would be a good idea to let customer know about sim network related to each product (Lyca/T-mobile/AT&T in case of USA).
I thought my simcard was T-mobile but it turned out to be Lyca…. my mobile bands were matching for T-mobile….so got only 2G network.
Services Tsim –
Thank you for your kind and balanced review. The mobile bands used by both operators is the same. We will investigate why you got only 2G speeds.
Rajan Ranganathan –
I was making a trip to USA for two weeks in the second half of February 2020. I was visiting New York City and Florida. I wanted to have my USA sim card before I left. I did a lot research on the net to find out which phone service would be the most functional and the most cost effective. TSIM stood out in the analysis. It had received a lot of good reviews on the product as well as on customer service. So I ordered one t-mobile sim card from them.
In the meantime I started using their Whatsapp chat to get all my questions clarified. The response from their Whatsapp chat was amazingly quick and to the point. They expertly guided me as to which Indian phones would work in USA and which not. That proved very useful while I was in the USA.
Once I ordered, I was kept informed regularly about the status of the order. It arrived on time and was activated on time before I left India.
Once in the USA, I had no problem connecting to t-mobile network using the Indian phone which they said would work. Data speeds were excellent with 4G connection both in New York and Florida. I was very impressed.
One small issue I faced. I was not able to check the data balance from my phone. I again contacted their Whatsapp chat from USA and they checked the balance for me in a flash and let me know.
Thank you TSIM for the excellent product and service.
Services Tsim –
Thank you for your kind words and detailed review.
MURALI NARAYAN –
For our recently completed trip to the USA in Feb 2020 which was a two week tour to over 6 states including St Francisco , Los Angeles , Las Vegas , New York , Washington and Miami , I finally opted for TSIM for my calling and internet services and this was after browsing over the net for nearly a week.
I saw the reviews were good and went for it and all readers trust me this is a powerful service and I had excellent and very strong connection all through my trip except for Grand Canyon in Arizona state which is very well understood as the contact person at TSIM had clearly informed me the same.
Every calling be it local US calls or even calls to India through a connecting number was superb and without any problem whatsoever.
Even the browsing was perfect and I am saying this as I did not face any problem whatsoever and once I returned to Mumbai I disconnected and the whole deal for a very economical price of 3489 is comfortably acceptable, at least for me.
I am thankful to TSIM and would highly recommend travellers to USA to prefer this product and hope they also get the same service as I was thrilled to enjoy during the entire trip.
Good Luck and All the very best TSIM.
Services Tsim –
Thank you for your detailed review and recommendation.
Hitesh Muchhala –
Good service. Got delivery of the SIM card at my home the very next day . Also the sim got activated correctly on the activation date and a prompt email arrived giving the mobile number. Query response was prompt. I had to take 2 months validity SIM card for usa whereas I needed for 45 days. They should have a daily package also if we want more than a month but less than 2 months. Otherwise it is fine. Keep it up
Services Tsim –
Thank you for your kind and detailed review. We do have a daily pack, but due to the pricing strategy of the operators, it is cheaper to take a 2 month package than a 45 day daily package.
sanjay –
Very good service and I have been using them since many years and everytime their service is excellent. I am very satisfied with the coverage and clarity.
recommend it 100%

Mrinali Rochlani –
I found their service excellent and very efficient! I had to leave suddenly, and I ordered their sim, a kind serviceman came and delivered it to me within 24 hrs, and collected the necessary documents, unlike other companies that take a week to deliver. I have tried 3 companies for international sims in Mumbai so far, and TSIM has been the best experience. I had very good internet and connectivity all over USA throughout my one month trip. I would highly recommend this company.
