Roaming vs eSIM Cost Comparator
Estimate how much mobile data you’ll use abroad, then compare your network’s daily roaming pass with a travel eSIM, a local SIM or paying per GB.
About this tool
Start with how much data you’ll use: maps and messaging use very little, but streaming video can use over a gigabyte an hour. Then add the deals you’re weighing up. A roaming pass is charged for each day you use your phone abroad, usually using your home allowance; a travel eSIM or local SIM is a bundle of data valid for a set number of days, bought again if you run out.
The example prices are placeholders: enter the ones your network and eSIM provider quote. Before buying an eSIM, check your phone supports eSIM and isn’t locked to your network, and keep your home SIM switched on for calls and texts if you need them. Your options are saved on this device.
