Is a travel eSIM cheaper than O2 roaming?
It often is for trips of more than a few days, because a prepaid eSIM is one payment for the whole trip. Compare O2's price for your plan with a Graba SIM plan for your destination.
How much is O2 roaming in the USA?
O2 lists 1 option for this: Germany Roaming Plus World / Schweiz packs. Prices without a figure depend on your plan, so check O2's official page. Confirm your destination is in the zone before you travel.
How do I stop O2 roaming charges on my phone?
Before you land, open Settings and turn Data Roaming off for your O2 line (iPhone: Mobile Service or Cellular; Android: SIMs or Mobile network). Turn off automatic data switching too. To avoid calls and texts being charged, turn the O2 line off or use Wi-Fi calling where O2 allows it.
Can I keep my O2 number while using a Graba SIM eSIM?
Yes, on a dual-SIM phone. Keep your O2 line on for calls and texts with its Data Roaming off, and set the Graba SIM eSIM as your mobile data line. O2 may still charge for calls, texts and voicemail abroad.
