Andy roaming means nothing here in the UK. Roaming costs will depend on network but they can be very expensive indeed. If you were going abroad for 3 days maybe you would just go ahead and encure the roaming costs of calls and texts but where it gets very expensive is in terms of internet and e-mail. There have been horrendous cases of people who have gone abroad for a couple of weeks and encurred hundreds of pounds from their service provider when back in the UK. I travel to Ireland a lot and when I do I use the Irish Sim for calls, texts and internet and e-mail. This way it is much cheaper on a pay as you go basis. ----- Original Message ----- From: ANDY COLLINS To: access-uk@xxxxxxxxxxxxx Sent: Saturday, December 08, 2012 3:28 PM Subject: [access-uk] Anybody explain how roaming works on mobiles? Hi all - Looking around the T-Mobile website for info on the above, they advise to turn off Roaming when abroad, so as not to incur charges. They also say that having Roaming turned on in the UK does not cost. I feel I don't properly understand about Roaming. What point is there to it in the UK, and when abroad, if it is on, does it mean that I would get charged whatever is the going rate in that country? When abroad, T-Mobile sell up front, waht they call Boosters, which allow so much data useage, such as 3mb for a quid, that has just a 24 hour life, I assume this is a better deal than leaving Roaming turned on, using the local providers? - Andy
