Calls or texts not working

Calls and texts use a different network path from mobile data — having working data does not mean calls and texts will work.

Step 1 — Check your eSIM line is set as the default for calls

iPhone: Settings → Mobile Data → Default Voice Line

Android/Samsung: Settings → Connections → SIM card manager

Step 2 — Check you have signal

Calls and SMS require mobile signal. They do not work over Wi-Fi unless Wi-Fi Calling is enabled.

Step 3 — Toggle airplane mode

Turn airplane mode on, wait 10 seconds, then turn it off. This re-registers your device on the network.

Step 4 — Restart your device

Step 5 — Test with a different contact

If other contacts work fine, the issue is with the specific number you're trying to reach.

Step 6 — Check for a network outage

Check status.gigs.com for any known issues.

iMessage and WhatsApp are not the same as SMS

These apps travel over the internet, not the mobile network. If they're not working but standard SMS is, the issue is your data connection — see ****My eSIM has no mobile data or is not connecting.
