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).

eSIM Details
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.

I had a wonderful experience with T-Sim in my three week long trip. I have visited Bay Area, Pheonix, New York, Boston, Indianapolis, Des Moines, and Chicago. Everywhere, I got 5G connectivity with good speed and no call drop. I would recommend everyone to try this if you are going for a USA trip.

TSIM’s international eSim service offers hassle-free setup and robust network coverage. I used their service on my recent trip to USA. Configuring my phone was a breeze with their straightforward instructions. Throughout my travels, I experienced consistent connectivity in both urban and remote areas, ensuring I stayed connected wherever I went. The network speed was impressive, facilitating smooth browsing and streaming. Overall, I highly recommend TSIM for seamless roaming, providing peace of mind and reliable connectivity on the go.

Sandeep Mahajan (Verified user) –
Perfect service on getting the card deliver at my home. Activation happened as per suggested date. Its working perfectly fine during my stay in US.
Local sim is needed to connect to Uber or other taxi services.
Even food delivery people need local number.
Best rate available.
Services Tsim (Verified user) –
Thank you for your kind review and for pointing out the utility of a local SIM.
Vaibhav Singal (Verified user) –
The sim worked but the process of installation was not clear and I had to call twice to provide details, get my phone registered for esim and understand the process
India calling did not work for my entire trip and support staff could not resolve the issue
Services Tsim (Verified user) –
We are sorry the eSIM installation process was confusing. In response to your comment we have altered our eSIM details page to better explain the process. We have also been in touch with the backend operator to understand why India calling could not be activated in time for your trip. We apologise for the inconvenience and thank you for taking the time to record your experiences.

During my recent trip to the USA, I opted for T-SIM’s Unlimited USA SIM Card, and I must say, it exceeded all my expectations. The convenience of unlimited calls and data, coupled with the ease of direct dialing, made my trip hassle-free.
One notable aspect of T-SIM’s service is its affordability. Despite offering top-notch features, the cost is reasonable, making it accessible to all travelers. However, it’s important to note that using a Chinese mobile, such as a Xiaomi or Mi phone, may not be compatible with the SIM card for data usage.
On top of the excellent service, I was pleasantly surprised to receive welcome gifts, including a Grooming Kit 7 in 1 and a USB Universal World Travel Adapter. These thoughtful gestures added to the overall positive experience with T-SIM.
In conclusion, I highly recommend T-SIM’s Unlimited USA SIM Card to anyone traveling to the USA. Its exceptional service, great value, and thoughtful perks make it a standout choice for staying connected while abroad.

I got number which was *misused* by previous user. When I landed in US, I started getting so many junk SMSs and junk calls. I’m not sure how frequent these numbers are allocated, but it’s torture to use it.

We have taken up your complaint with the operator. They have assured us that numbers will have a cool off period before reuse. Thank you for taking the time to record your experience and apologies for the inconvenience

The package is very good. However, we did face initial problems in getting the direct dialling to India, activated as per the package. Please streamline the system to avoid such hassles in a different country where one would not like to have.

A very fine and useful product , it is second time that I am using T sim. First time I used for Europe (Finland, Swindon , Denmark, Norway) and now I am using in USA. It is very much economic and have best connectivity, far better than Matrix and other brands which I was using previously.

Shantanu (Verified user) –
We purchased the 15GB high coverage SIM and it was delivered to us within 3 days. We didn’t face any connectivity issues in Las Vegas, Los Angeles, Merced, San Francisco and bay area. We did face some connectivity issues in Yosemite but that was still better than other operators.
A limitation we experienced with TSIM is that the phone number associated with SIM is available only when you land in US. This was an issue as we had services with which we wanted to share a US contact number but couldn’t because of this limitation. We found a workaround by sharing emails wherever we could and made it work. Deducting 1 star for this limitation.
In case the SIM you purchase doesn’t work, TSIM has a whatsapp support number which is very helpful. TSIM support responds fast when you need it.
I would also recommend getting an eSIM though if you are going to use this SIM on an iPhone. Having an eSIM will let you operate your iPhone in a dual SIM manner.
Overall 4 stars for hassle free experience.

On the day of your activation, our systems failed to send activation and phone number emails for a few hours. Unfortunately your sim card was activated then which is why you did not receive an email with your phone number. We thank you for your balanced review and apologise for the inconvenience.

SIM did not work for two days after I reached USA and had to specifically send a SMS from another number to get it going. And next even though we were touring only main cities – NY / WDC / BUffalo / SFO / LA / Las Vegas – there was a never a case where the data went beyond “E”

Even though I live in a very remote area, it was wonderful that the SIM card arrived right at my doorstep. And it started working as soon as I landed in the US. Though I had wifi access where I was staying as well as at my conference venue, the data service was so helpful when commuting when I needed to use my GPS. And the cost was reasonable too.

Dr. Sanjeev Bhandari (Verified user) –
Activation on arrival at USA airport was instant & data speed is good. But T-mobile coverage is not good at many places, even in San Francisco bay area & many times, I have to call through WhatsApp as routine local calls cannot be done.

Dilip (Verified user) –
No signals in areas like Canyonland National Park, Arches National Park, Bryce National Park or ZION National Park in UTAH as also in upper antelope in Arizona.
In other places, sometimes signal is weak (only one or two bars)
Barring this SIM is OK.
I am regular customer of TSIM and happy with services.
Services Tsim (Verified user) –
For remote areas we do recommend high coverage options. We are looking to increase the number of high coverage options and reduce their prices and should be able to do so soon.

Abahy Sagade (Verified user) –
The purchase and delivery service was straightforward. The sim was active and working once the phone was started in the US. In NY, coverage and service are also fine.
I have the following problems:
– T-sim allows ONLY monthly choice of package. There is no mention that a month is of 30 days. It don’t consider 31st day in a month. This is disastrous. Imagine if you are travelling out of a country on the last day, you won’t have a network service (dead sim). Then how to contact people and arrange travel. I informed it to T-sim several times, but there is NO positive action from them.
– T-sim mention ONLY T-mobile and AT&T network on the website. But in reality most of the time the delivered sim is of Lyca mobile. Though mobile selects service from T-mobile and Lyca automatically.
– When I reported problem above #1 to Lyca, they said they had nothing to do with this or T-sim. LYCA REFUSED TO HAVE ANY CONNECTION WITH T-SIM. This is horrible. So, I am in trouble with my 4 months plan, I WILL NOT HAVE A NETWORK/SERVICE IN THE LAST THREE DAYS OF MY STAY IN THE US. BOTH T-sim or Lyca said they CAN’T do anything about it. THIS IS A CHEATING and FRAUD. The number of days option is given in other plans, but not for the USA.
Plz be careful while selecting plan.
Services Tsim (Verified user) –
It is true that generally operators in USA describe their 30 day plan as a monthly plan. We use the same terminology for easy comparison of offers. However this was informed to you by email on 29th August before your travel along with an offer to refund. Asking the same question to the operator will only give you the same answer. Thank you for taking the time to point out this issue to our travellers.

It did not work even in airports like Detroit. Data works well but calls are very poor.
