When you land
Four settings, once, after you touch down. Your plan's days start when the eSIM first connects there.
The four steps
- 1
Turn on the eSIM line
When your iPhone asks, tap Turn On Travel eSIM. Or switch the RoamClean line on in your SIM settings. - 2
Set it for mobile data
Choose RoamClean as the line for cellular or mobile data. - 3
Turn on data roaming for it
Data roaming on, for the RoamClean line only. Our network partner requires it: the eSIM connects as a roaming line. - 4
Keep your home line on for texts
Leave your home line on for calls and bank codes, and turn data roaming off on it so it can't run up roaming charges.
On iPhone
With iOS 26 and later, your iPhone may do steps 1 and 2 for you.
- 1
Tap “Turn On Travel eSIM”
Choose Travel eSIM and Current eSIM to keep your home number on. Apple: “your travel eSIM will be used for data.” No prompt? Settings > Cellular > tap RoamClean > Turn On This Line. - 2
Check the data line
Settings > Cellular > Cellular Data > choose RoamClean. - 3
Data Roaming on for RoamClean
Settings > Cellular > tap RoamClean > Cellular Data Options > turn on Data Roaming. - 4
Home line: roaming off
Tap your home line > Cellular Data Options > Data Roaming off. Also turn Allow Cellular Data Switching off.
iOS 26 also offers Low Data Mode when the travel eSIM turns on. It pauses automatic updates and background tasks off Wi-Fi, which makes your data last longer.
On Android
- 1
Pixel: choose the SIMs
Settings > Network & internet > SIMs. Set Mobile data to RoamClean and keep Calls and Texts on your home SIM. Turn Automatic data switching off. - 2
Pixel: roaming
In the same SIMs screen, open the RoamClean SIM and turn Roaming on. On your home SIM, turn it off. - 3
Samsung: choose the SIMs
Settings > Connections > SIM manager. Make sure RoamClean is switched on, then under Primary SIM set mobile data to RoamClean and calls and texts to your home SIM. - 4
Samsung: roaming
Settings > Connections > Mobile networks > turn on Data roaming. Your home SIM isn't carrying data, so it won't use roaming data.
Good to know
Give it a few minutes
The first connection can take several minutes, and occasionally up to an hour. Leave the phone on and keep it out of airplane mode.
You'll see the local network
The top of your screen shows the local network, such as Telcel or AT&T in Mexico, not RoamClean. Why.
Still no internet?
Work through the No internet? checklist. It takes about five minutes.
Bank codes and texts
Your home number keeps receiving texts. More on keeping your home number.
