04 — FAQ

Questions, answered.

Is my phone compatible?

Most phones from 2019 onward support eSIM — iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer. Your phone must be carrier-unlocked.

How are you cheaper than everyone else?

We buy data wholesale directly from networks, run lean, and skip the big ad budgets. The savings go straight into the price.

When does my plan start?

Validity begins the first time your eSIM connects to a supported network at your destination — not at purchase.

Can I keep my regular number?

Yes. Your physical SIM stays active for calls and texts while BesteSIM handles mobile data.

What if I run out of data?

Top up in seconds from My eSIMs. No new QR code, no reinstall.
