- Power off your phone
- Insert your new SIM card
- Power on your phone
- Your phone should connect on a GSM/WCDMA/LTE network.
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.

Worked well in New Jersey, Chicago and Orlando. Service is good and very economical
Services Tsim –
Thank you for your kind words and for confirming the areas in which it worked.
Paresh Vora –
Used this card in May-June2019 during our recent visit to US. This card is very cost effective. We stayed for nearly all days in Bay Area, where the card worked very well. I also visited New Jersey for 2 days. In New Jersey, the connection was very spotty, with connection getting broken or in many places simply showing no connection.
Services Tsim –
We apologise for the spotty connection in New Jersey. Thank you for your kind words and balanced review.
Dr K N Poddar –
I purchased the USA sim for my 7 days trip. Connectivity is excellent. Internet speed is very good. It’s the most economical sim available for USA.
Services Tsim –
Thank you for your kind words.
Dr. C S Sharma –
Good product. Good delivery. Good price. Good connectivity in USA. Contacting them on phone is very very very difficult after you have made payment. . Therefore 3 stars.
If you understand a DC follow all their website instructions 100% all will be fine. If you have deviations, returns, reissues there will be difficulties. Biggest problem I faced was get them on phone. But in the end all was fine. In US the connectivity was superfine. On my next visit I will use this service only. I am giving them 3 stars in the hope that they will improve their system of responding to customers calling them to talk to them to seek clarifications after making payments.
Services Tsim –
Thank you for your kind words and detailed feedback. We will surely try to improve our telephonic support.

This SIM card is very good. When I landed in Seattle just turn on phone and it start working without any issue. I could able to talk to my family immediately. Service was good in US and I have not trouble to get signal. Internet was slightly slow but off course my phone was also old. Overall its good experience I will recommend others to enjoy Tsim.

S.Preethi –
Poor signal quality . Mobile internet was pathetic.
Services Tsim –
We had informed you that your phone was not compatible with 3G and 4G networks in USA. Due to this your Internet would have been slow. Thank you for your review.
ashoke keswani –
very good and economical product
Anivesh –
The signal reception and 4G internet speed on my 10-day unlimited package was great. The only problem i faced that on the 10th day of my trip, the sim did not receive signal anymore. I guess T-Sim counts 10 days per Indian time. I had written email that I am unable to use the service on 10th day, but no reply.
Biswanath Debnath –
Phone calls and SMS were all right from the beginning – in fact, I started receiving SMS right after activation, even before I left India. Internet connectivity had initial teething issues, but were resolved. Overall, good experience. Just one issue: I purchased my SIM for one month’s duration and spent 10 days in the USA. However, upon return home I find that SMS reception has been blocked.
Services Tsim –
Thank you for your kind words and review. These cards are meant to be used outside India only.

I didn’t face any network issues while using TSIM. The speed was also quite high.
Among all the available options that I explored, TSIM’s pricing scheme was the best.

Services Tsim –
Thank you for your kind words and continued support.
Suryansh Gaur –
Great service, got good connectivity both for calling and data all across SFO. Worked smoothly since the time i landed at the airport. Customer service needs to improve a bit in being prompt enough to provide activation details along with phone number, in my case I had to follow up to get things done.
Services Tsim –
We apologise for the inconvenience of the activation process. We will be inspecting the details of your case to see where we can improve the process. Thank you for detailing your experiences and your balanced review.

I was initially skeptical of trying a new service.. but this has been by far the best experience I have had. The sim card connects seamlessly both voice and data and you are never worried of receiving calls, making calls to India and data usage.
I would definitely recommend Tsim always.

Works very well in the USA.
I was not able to use data on landing, I had to call tsim MUMBAI for help.
They were very helpful and were able to solve my issue by showing me how to update carrier settings.
The only reason for giving 4stars.

TSIM has provided me a marvellous and wonderful service ! I have used it in California and never got any problem. It had superb connectivity, clear voice coverage and good internet. TSIM is truly value for money. This is the sec9nd time I am using TSIM in USA and I am completely satisfied. Besides, back in India, TSIM has an excellent support team via tele-talk as well as WhatsApp. I will recommend TSIM to everyone I know or come across in future!
Malay –
H2O sim worked fine in Boston, NYC, Baltimore, Washington and Atlanta city. Though It was a 4G sim, because of compatibility of network with my mobile, I got only H+ and not 4G. But speed was quite okay.
One point where Tsim can improve in their service is that they should able to tell the customer clearly which frequency bands are used by AT&T (or Tmobile) at particular area of interest, so that one can understand the compatibility of his/her phone with network. The information I got from customer service that ‘my phone may or may not work with the network depending upon availability of 3G network’ even when I clearly mentioned the bands of my phone. This type of information is not helpful at all. So I had to contact AT&T and confirm the bands they use in these cities. Tsim should have these basic info with them to serve better.
Services Tsim –
Thank you for detailing where the SIM card worked and for your suggestion. 2G & 3G networks in the USA are rapidly being dismantled making any information we have outdated very soon. However, we will certainly look to be able to provide more detailed city wise information.
