my son is going to canary islands tommorow. He still has his voicemail activated and there is no one answering at three network to deactivate it. His flight is early in the morning.He also hasnt let three know that he needs to use his phone abroad. So not sure if it will work??
It should work. Three will be bound to have a roaming agreement with some telecom company. Just make sure he turns off the data roaming (if it`s a smartphone)
It won't work if he hasn't activated data roaming with his provider (well, we have to activate it for our network with 02) but he can always ring them from the airport. Agree that any data updates should be turned off, they can cost a fortune if they still happen while he's out of the country. Is there no way he can do it online with 3 Network?
