How to enable data roaming on Xiaomi / POCO / Redmi

Direct answerOn a Xiaomi: Settings → SIM cards & mobile networks → Data roaming → International roaming → pick "Always". A travel eSIM works "in roaming" on top of the destination’s local network — turning on roaming for the eSIM line creates no extra charges, the plan already covers it. The line that should have roaming off is your home line.

The exact path

Xiaomi / POCO / Redmi: Settings → SIM cards & mobile networks → Data roaming → under International roaming pick "Always"

Why does the eSIM need roaming turned on?

A travel eSIM is a line issued in another country that connects to your destination’s local networks "in roaming". Without that switch on, the phone shows signal but nothing loads. It’s the world’s most common eSIM mistake — and the fastest to fix.

And my home line?

Leave your home line (Verizon, AT&T, Vodafone, EE...) with roaming off so you never pay your carrier’s international roaming rates. It keeps receiving SMS (bank codes, etc.) at no cost.

The 60-second checklist (fixes 8 out of 10 cases)

Data roaming turned on for the eSIM line (the world's #1 cause)
eSIM line selected as mobile data (not your home line)
eSIM line turned on (the "Turn On This Line" switch enabled)
Airplane mode for 10 seconds → off. Still nothing? Restart the phone
Still nothing? Manual network selection: pick a local carrier from the list

Frequently asked questions

Why does it have to be on "Always"?

Xiaomi’s factory default blocks data on international roaming even with the main switch on. Without the "Always", the eSIM installs but never gets online.
