About this tool
Roaming bills come from daily use times days times price per megabyte. This calculator multiplies those three numbers, with an option to compare against a fixed travel bundle. Prices vary wildly by provider and destination, so confirm your roaming rate before travelling.
Frequently asked questions
How do I cut roaming costs?
Use hotel and cafe Wi-Fi, download maps offline, and consider a local SIM or travel eSIM for heavy use.
Does the price include calls and texts?
No. This covers data only; calls and texts usually have separate roaming rates.
