Read the plan’s start rule first
Hardware compatibility is the first check. Also confirm the phone is unlocked, the plan covers your destination, and your trip fits its data allowance and validity. Check whether the plan includes calls or texts, whether hotspot use is allowed, and when its validity begins.
Installation and activation are separate events, but providers define start rules differently. Follow the exact plan’s instructions before deciding how early to install. A compatibility result does not verify a plan’s coverage or current availability.
Install while you have a reliable connection
Use the installation link, QR code, or manual details supplied by your provider. On an iPhone, a supported QR code can be scanned with the Camera app; on supported iOS versions you can also press and hold a QR code in a supported email or browser. Samsung uses Add eSIM in SIM manager.
Roamzo provides an Install eSIM option in the order, plus QR and manual installation. Keep the private order link and installation details to yourself. This checker is managed by Roamzo; purchases and plan support are handled on Roamzo’s website.
Choose the travel line for mobile data
When you reach the destination, follow your plan’s activation instructions. For a Roamzo travel eSIM:
- Turn on the travel eSIM and select it for mobile data.
- Enable data roaming for that travel line as instructed by Roamzo.
- Turn off automatic cellular-data switching to reduce the risk of falling back to your home line.
- Check your home carrier’s charges before leaving its line enabled for calls, texts, or roaming.
If it does not connect
Check destination coverage, remaining data, validity, and the selected data line. Ask the provider for help before deleting the eSIM: reinstalling may require its assistance. For a Roamzo purchase, open support from your order or use the support and contact page.
