When I visit Ukraine, my phone does not connect to a local network. Does giff gaff have a problem with this country?
Depends where in Ukraine. Kyiv or Lviv you'll be fine. Out in the sticks no. If you have a 4g phone you need to turn 4g off as there's no 4g roaming agreements in place (nor is the 4g really existant in Ukraine)
Do a manual roam and search for Kyivstar, MTS or Life 🙂 You'll more than likely connect to Kyivstar or MTS and then you can use credit to make calls.
