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.

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

Activating eSIM on your Device using an Operator Notification

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#.

I used this card in New York. Fairly good network.I took a basic 1 Gb plan. Was very apprehensive about network, coverage, etc. But It was okay. No complaints. But 1 Gb data got exhausted within a week. Over all I would come back to Tsim when I plan my next trip because of value for money plan.
Services Tsim –
Thank you for your kind words. 1GB is enough for just about a week of use. For trips upto a month we recommend 4GB plan or more.
Services Tsim –
Thank you for detailing where the SIM card worked. The SIM card you took does not usually allow hotspot.

I would strongly recommend T-Sim for the east coast, as I traveled for a month and did not faced a single issue. The service and connection was hassle free. Keep up the good work.
Aditya –
Go for it blindly. I had serious trust issues with such a sim that offered unlimited data for such a low amount ( in comparison to matrix etc) . But man it worked so well all throughout USA. Full signal strength. I consumed 28 GB in 12 days . Full Customer support was there.

I used this card while traveling in USA (west coast) the coverage was excellent without any call drop. The service is too good and what they charge is very less compared to other service providers.

I had purchased for USA 1 month 4GB card. I was activated on 2nd August, 2018 and lasted until 30th August, 2018 (my date of return). The card worked seamlessly for calls made and received at New York, Washington, Buffalo, Las Vegas, Los Angeles, San Francisco, Huston, Detroit and New Jersey. It also worked well for internet whenever required. I highly recommend this card in USA because you get USA number with this. That is convenient for USA residents to call you. Besides, it works out cheaper

Thank you for your kind recommendation and for detailing all the cities in which it worked.

I am very glad with the services of TSIM. I purchased Rs 1489 plan with 4GB of data. I faced no issue with network while in Raleigh, NC and Austin, TX. No call drops.
Best and cheapest plan to choose if coming from India to US.
Services Tsim –
Thank you for your kind words and for confirming the cities in which it worked.
Adip bali –
Outstanding service. Did not have any problem at all. Was in Washington DC and Raleigh Durham area . Both voice and data connectivity was outstanding
Narinder –
Calling was just about acceptable. Did not get the data despite repeated attempts. Could not call Uber. Faced very major problems. Look for something else even if it costs you 5 times.
Services Tsim –
We wish you had contacted our helpdesk when you faced these problems. We have no way now of finding out what caused inability to access data. Thank you for your review.
Sachin S. –
Before concluding the sale, the customer service/sales team called us and made sure that I have a phone suitable for the frequencies used in the US state of our interest. They were very helpful in explaining the benefits of the card, and instructions. We were provided a [trademark removed] card.
The card worked perfectly as we had wished and planned, for all promised calls as well as internet/ data.
We wish to renew, and highly recommend this card to all visitors to Georgia State.
Services Tsim –
Thank you for your kind review, for confirming the state in which it worked, and for your continued support.

I would definitely rate the service provided by tsim.in as super excellent. Anyone going abroad, specially to the USA, should take a SIM from tsim.in. Just to clarify I’m not related to anyone at tsim nor do I have any business interests in this co. I’m a simple Thanekar, who travels to & from Thane & Parel in a local train daily. I took this SIM for a short trip to New York in the beginning of Aug 2018. I was really very skeptical about their service as I did not hear about tsim.in’s service from anyone & was afraid that I’ll loose my money. Still I went ahead and purchased their SIM online. It cost me somewhere around Rs 1050 for one month unlimited USA local & from USA to India calls with 1GB of 4G data & thereafter 3G data speeds. I must say my whole experience was butter smooth. As promised the SIM was delivered on time. It was activated on time. The tsim.in team was updating me with the current status of the SIM till activation. The team is really very helpful. I was able to use the SIM very well all through the trip. The SIM was genuinely unlimited. I made long calls to India to my parents & friends from the US & also was able to make unlimited calls within US using this SIM. I was even able to help an old couple from India waiting at Newark airport for their flight back to India which was delayed due to some technical issue by lending them my mobile for making a call to their son/daughter in the US informing about the delay. A very nice experience with tsim.in I must say. Thanks for going thru this long post.

Arun Prakash R –
very good deal and network connectivity is good in all the places where i traveled, CA, AZ & GA , NYK but What I faced issue , whenever my phone is connected to WIFI , whether at hotel or my office , unable to receive call from others and gives the message out of coverage , where they call next to me, still with good network range , when I switch off WIFI , I will receive calls and also I can call.
Services Tsim –
Thank you for detailing the cities in which it worked, and also for bringing this issue to our notice. This indeed seems to be a problem with some phones, wherein they attempt to switch you to WiFi calling in the presence of a WiFi network, and as a result cause problems in reception of calls. One workaround is to switch to 3G mode on the phone. We apologise for the inconvenience caused and thank you for your balanced review.
Kunal Mahajan –
Price of the sim is worth but there is a problem with the network. I am not sure that is because of network or because of the phone I am using.
Services Tsim –
Your phone is not compatible with the network on 4G, and only 50% compatible on 3G. This is the reason you faced network issues. Thank you for your review.
Gautami Shah –
I used the simcard in California area. While the activation and delivery of simcard was timely, I was extremely disappointed with Tsim’s transparency. Firstly, the website mentioned that a T-Mobile sim will be issued however I was actually given a (brand name removed) mobile simcard. Further, the worst part was that I was receiving fraud/hoax/promotional calls from random USA nos. continuously. I received nearly 1000 such calls over a span of 17 days. I think this is serious and can only be blamed on the simcard company (brand name removed) that is recycling these nos. so often. It is not only a nuisance for the traveller but also a disturbance when you are on vacation.
I think this needs to be taken seriously. I will be happy to share the details of which nos i received calls from.
Kindly look into this on priority.
Services Tsim –
We are extremely sorry for the nuisance calls, as well as for your impression that it will be a T-mobile card. The website calls it a T-mobile based card, which is to say it works on the T-mobile network. Usually these are MVNOs (mobile partners) of T-mobile or AT&T that provide the card.
We will be in touch with you regarding the nuisance calls and will take it up with the operator. Thank you for your balanced review and understanding.

The SIM was delivered on time. Processing was smooth. Network availability was good at most of the places visited. Internet was slow and many places mobile data was very poor.
Overall Very good and highly recommended.
Services Tsim –
Thank you for your review and understanding. We are sorry that the network speed was not satisfactory in some places.

Girish –
I have been customer with TSIM for past 5 years. I used to travel every year to Europe. This time I was travelling to USA and the SIM was magical. It made life easier. I did not have to think twice before making a call.
I did experience low or no network in some locations, specially in Orlando. But overall it was superb. Since my mobile Mi was not compatible for Mobile data, the advice of not taking package with more data was useful. WiFi anyway was available in the hotel.
Thank you for this wonderful option. Now I am your permanent customer.
Services Tsim –
Thank you for your glowing review and continued support.
