Personally I don't really care as in the grand scheme of things its not a lot of money when considering the cost of a holiday.
The people it will have the biggest impact on are those who spend a few months a year in Spain, or visit such places regularly.
I can already hear my FiL complaining. And will have less than zero sympathy.
When I go abroad on holiday I only use my phone when there is wifi available otherwise I just use it for the camera. Got caught out once, never again. But then again I am old and don't understand most things about mobiles.
EE in the story are charging £2 per day if you want to use roaming. Not a lot I agree, but and additiional cost non the less.
There will those who fall foul and run up large bills (Hopefuly no more than £50)
The 25GB is a fair use limit that o2 are putting, most will have had one anyway.
I fully expected to be charged for roaming once we left the EU. IMO it's a good excuse for the phone companies to make more money without being constrained by the rules of the EU.
However, if I am on holiday abroad, I do not use my phone heavily. I may use it to browse to check up on news, sport, etc but most places now offer WiFi for free but for me my holiday is for relaxing. Not browsing the phone.
It's like watching a couple go out together to a restaurant and then they just sit there on their phones. We have a rule that if we're out, the phones stay in our pocket.
I read my message from O2 as being that i will still get unlimited calls & texts whilst abroad (in EU). And that in Europe, if your current UK data limit is 25GB or above, data will be capped at 25GB. If your existing limit is less than 25GB, then it stays at your current limit. In either case, you get charged handsomely if you go over your limit. For me, no issue. Send few text messages, make even fewer calls and never get near my 8GB of data.. So no change.
The roaming thing happens behind the scenes to an extent. I was on holiday in Croatia a few years ago, EU country, and did a day trip to Montenegro, not an eu country. I took my phone with me to take pictures but didn't use it in any other way. Next bill came through and I'd been charged for roaming for that day. The phone company refunded the amount when I queried it, they didn't have to, and explained how the phone searches and links even when not in use. Lesson learned.
Next time we did a similar trip I went into settings and turned roaming off.
Since my phone is a work tool, its switched off at the airport flying out, and switched on after baggage claimed. I use a wifi only tablet for personal email contact and browsing on the lounger. Holiday is just that, not an extension of my work life
