United States Unlimited   / Boston Harbor

The validity of a package that is already running cannot be extended, but you can top up: a top-up adds a new package with its own data AND its own validity days. Packages run one at a time - the top-up waits in queue and activates automatically when your current package ends (data used up or days expired), and its own days start counting from that moment. In practice this keeps you connected longer, even though the current package's own end date does not move.

The validity of eSIM plans varies from 7 days to 90 days depending on the plan you choose. Lifetime options are also available for travelers who don't want their data to expire after a fixed period.

Most modern devices support eSIM, including iPhone XS and later, Samsung Galaxy S20 through S25 series, Google Pixel 4 and later, Huawei P40 and later, and many recent iPads. Check our full compatibility list before purchasing to confirm your device is supported.

Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.

eSIMno is an excellent option for travelers heading to United-states-unlimited. We offer a diverse range of eSIM plans - including regional, local, and lifetime options - with reliable coverage on local networks.

eSIMno partners directly with local operators in over 200 countries, eliminating intermediaries. This direct relationship lets us offer competitive pricing, extensive coverage, and faster activation than resellers who route data through third parties.

Yes. eSIMno sends email and push notifications when you've used 50%, 80%, and 100% of your data allowance. You can also check usage anytime in the eSIMno Center or in your phone's cellular settings to track consumption in real time.

eSIMno is a data-only service, so you can't make traditional voice calls or send SMS through the eSIM line. However, you can use messaging and calling apps over data - WhatsApp, iMessage, FaceTime, Telegram, Signal, and Google Meet all work normally.

Yes - setting it up before your trip is the easiest approach. Your confirmation email contains the QR code, a one-tap install link and the manual SM-DP+ / activation codes (the same options are also available via sign in > Profile > My eSIMs > Install). While on Wi-Fi at home, install it with the one-tap link on your phone, or - to use the QR - show it on another screen or a printout and scan it with the phone you are setting up (not another phone). Installing does not start your plan: the validity countdown only begins when the eSIM connects to a mobile network inside your plan's coverage area. Keep the eSIM line and its Data Roaming off until you are ready to start - if your plan covers the country you are in right now, turning the line on connects and starts the countdown immediately, even if you do not browse anything. Please note: once installed, an eSIM is considered used and is no longer eligible for a refund.

Unlimited plans provide unlimited data at high speed (4G/5G) up to a fair-use threshold defined per plan. Beyond that threshold, speeds may be reduced to 128 Kbps for the remainder of the validity period - still usable for messaging and basic browsing, but slower for streaming and video calls.

Yes - eSIMs typically connect within seconds of switching off airplane mode at the gate. Major airports have strong cellular coverage from local partner networks, so you'll have data before reaching baggage claim. No setup needed at arrival.

Coverage depends on the partner network's reach in United-states-unlimited. Major cities, tourist areas, and highways typically have strong 4G/5G coverage. Remote rural areas may have weaker signal or fall back to 3G. Download offline maps before heading off the beaten path.
