Question 1

When does my data plan start?

Accepted Answer

Your Global eSIM data plan activates when it first connects to a supported mobile network, usually when you arrive at your destination. The validity period starts from that moment. Each plan is valid for a fixed duration (for example, 30 days). If purchased in advance, you can install the eSIM earlier and it will activate only when it connects to a network.

Question 2

Can I make phone calls and send messages with my eSIM?

Accepted Answer

TNS Global eSIM plans are available as data-only or as bundles. Data-only plans provide mobile internet access, while bundle plans include data, calling, and SMS. With data-only plans, you can still make calls and send messages using apps like WhatsApp, FaceTime, Messenger, or Signal.

Question 3

On how many devices can I use the same eSIM?

Accepted Answer

An eSIM can be installed on one device at a time. If you change phones, you can transfer the eSIM to a new device after deleting it from the original one. Once transferred, it cannot be reinstalled on the original device.

Question 4

When will I receive my eSIM?

Accepted Answer

Your Global eSIM is delivered instantly after purchase. You will receive a confirmation email with installation instructions, including a QR code and a manual setup option. Once issued, the eSIM is ready to install and cannot be returned.

Question 5

Can I keep my WhatsApp number?

Accepted Answer

Yes. You can keep your existing WhatsApp number without changing any settings. As long as you do not register a new number in WhatsApp, your current number will continue to work normally.

Question 6

How can I check the usage of my plan?

Accepted Answer

You can track your data usage and manage your Global eSIM through the TNS eSIM app or by logging into your account on the TNS website. You can view remaining data, plan details, and manage active eSIMs at any time.

Question 7

Can I reuse my eSIM?

Accepted Answer

In many cases, you can recharge your eSIM without buying a new one. When available, top-up packages will be shown for your eSIM before and after purchase.

Question 8

How do I check if my iOS device supports eSIM?

Accepted Answer

Most iPhones from iPhone XS and newer support eSIM. Go to Settings > Cellular (or Mobile Data) and look for the option to Add eSIM or Add Cellular Plan. Make sure your device is unlocked, as carrier-locked phones may not support eSIM.

Question 9

How do I install and set up an eSIM on my iOS device?

After purchasing your TNS eSIM, you’ll receive installation details via email or the app. With an internet connection, go to Settings > Cellular > Add eSIM, scan the QR code, and follow the on-screen instructions. Set the eSIM as your mobile data line.

Question 10

When does my eSIM data package expire?

Your eSIM data plan becomes active when it first connects to a supported network. The validity period starts from that moment, not from the purchase date. Once the duration ends or data is fully used, the eSIM expires.
