Can I use my mobile data while there or just use the wifi and turn the data off I'm with 02
As far as I know, there are no roaming charges for mobiles in Tenerife/EU, so your phone should cost you the same as at home. You will be hooked up to a local provider and will get the same services as you do now.
However, if you go over your allowances it could be very expensive.Edited: June 07, 2018, 10:04 pm
Oscar is right there are no mobile phone charges for phoning Uk from Tenerife or anywhere in the EU .
I know this wasn’t the question but be aware that if you phone FROM the UK to anywhere in the EU you will be charged at a much higher cost . I learnt this when two few minute calls to the Republic of Ireland cost me nearly £4 . :(Edited: June 07, 2018, 10:12 pm
