Questions before you buy

Will it work on my phone?

Most iPhones from XS, Pixel 3 and Galaxy S20 onwards, if carrier-unlocked. Look for an EID in Settings → General → About.

When should I install it?

Before you leave, on Wi-Fi. It shows "Activating" until you switch on data roaming at your destination — that is normal.

Can I top up?

Yes, from My eSIMs or the app, without reinstalling.

What if it does not work?

Chat with Syla first: most install issues are fixed in minutes. Refunds follow our Terms of service.

Does it come with a phone number?

Data-only plans have no phone number: call and message over WhatsApp, FaceTime or a similar app. Some unlimited plans for the United States also include calls & SMS; they are marked “+ Calls & SMS”. For any question about calling with those plans, chat with Syla before you buy.

Is unlimited really unlimited?

It depends on the plan. Plans marked “True unlimited” have no allowance after which speed is reduced. The other unlimited plans for the United States run at full speed for the first 1 GB each day, then at 5 Mbps.
