Keep your UK mobile number active for calls and texts on your main SIM. HelloRoam runs travel data on a second eSIM line on any dual SIM compatible phone. No need to choose between your EE or Vodafone line and your holiday data. Your wireless connectivity abroad stays separate from your home plan, so there are no bill surprises when you return.
HelloRoam eSIM connects to 204+ carrier networks across 185+ countries. Your phone picks the strongest 4G or 5G signal in Custom Regions with no manual carrier selection needed. That breadth of network access means consistent cellular coverage whether you are in a city centre or a quieter coastal area.
HelloRoam sends an alert when you reach 80% of your data allowance. Top up from your account dashboard in seconds. A pay as you go eSIM with no contracts and no surprise bills on holiday. Managing your internet abroad this way keeps costs clear and predictable from start to finish.
HelloRoam eSIM connects to local 4G LTE and 5G networks in Custom Regions at local data prices. You get fast speeds for navigation, video calls, and streaming without paying EE or Vodafone daily roaming rates.

One QR code, no border hassle. A single regional plan gives you mobile data and wireless connectivity across multiple countries without ever swapping a physical SIM card.
