Frequently Asked Questions
Does this USA eSIM cover Hawaii?
Yes. This plan covers all 48 contiguous US states plus Hawaii. Alaska and Puerto Rico are not included. If you're traveling to Hawaii, this plan works perfectly — T-Mobile's 5G coverage in Hawaii is excellent.
Is a US phone number included? Can I make calls?
Yes. The plan includes a US local +1 phone number with unlimited calls and texts within the United States. This is relatively rare among travel eSIMs and is especially useful for booking restaurants, ordering food, or receiving local verification codes (OTP).
Can I use hotspot / tethering to share data?
Yes. Full hotspot and tethering support is included. You can share your data with a tablet, laptop, or another traveler's phone. This is particularly useful on road trips where multiple passengers need to stay connected.
Why should I only activate after arriving in the USA?
Because your validity period begins on the day you first activate. If you activate before departure, your days start counting down before you've even landed. Submit your activation details in advance, but wait until you're on the ground in the US — T-Mobile will send an installation push notification at 8:00 AM PST on your arrival date.
What if I don't receive the T-Mobile push notification?
First, make sure your phone is connected to Wi-Fi and that push notifications are enabled. If you still don't see the notification, use the QR code included in your activation email — scanning it works exactly the same way. If you need further help, contact eSIMKitStore support.
Will a phone bought in mainland China work?
Mainland China model phones (Huawei, Oppo, Vivo, Xiaomi CN variants) may not be compatible with T-Mobile's network because they support different frequency bands. Before purchasing, verify that your device supports T-Mobile bands: B2 / B4 / B12 / B66 / n41.
How do I submit activation details? Where is my EID?
After purchasing, click the link in your confirmation email, or go directly to esimkitstore.com/pages/activation-date. Your EID is in Settings → General → About on iPhone, or Settings → About Phone → Status Information on Android. It's a long number starting with 89049. Please submit at least 1 day before your arrival.
How far in advance can I buy this eSIM?
You can buy it as far in advance as you like. The eSIM will be delivered to your email within 24 hours of purchase — just save it and wait until you arrive in the USA to install it. The earlier you buy, the more time you have to submit your activation details and prepare.
