Our support team answers in English, French and Arabic, any hour.
An eSIM is a SIM card built into your phone. Instead of putting in a plastic SIM, you add it from your phone's settings and the plan downloads. You can keep your physical home SIM in at the same time.
Yes. Leave your home SIM switched on for calls and texts, and set Roam Caller as your mobile data line. Your WhatsApp account stays on your home number. Your home network may charge for calls you receive abroad.
Validity starts when the eSIM first connects to a network in your destination, not when you buy it. Buy a week early and install it at home.
Yes. Top up from your account or from the link in your email. The new data lands on the same eSIM, so there is nothing to reinstall.
Pay in Naira by bank transfer or with a local debit card. We handle the currency on our side, so your card's dollar limit doesn't come into it.
If you haven't installed the eSIM, you can get a full refund within 30 days of purchase. If it was installed but never worked, our support team will fix it or refund you.
