How can I prevent massive charges whilst in USA

[amici-pat]

I have 2 pay monthly accounts with o2.

I will be spending 2 weeks in USA and want to avoid large bills on return.

Quite often I get phishing calls and or voice mails from various companies, and if I don't recognise the number I do not answer, but I assume I will be charged for receiving voice messages.   How can I stop this from happening?

I have also recently been receiving messages from 02 regarding downloading aps for making calls via wi-fi, not sure what this is about, but will I also incur charges for these?

For the first time ever, this month I have received a warning that I have used 80% of my data allowance, and cannot think what this would have been for.

Any help would be gratefully appreciated.

Problem is ....you cannot! I was in the USA for 22 days, evidently over two billing periods and O2 charged me £40 extra for each period!! I even shut off my smart phone. But, when I complained they said that it was texted to me that the charge would be an extra £40. It was not clear that the £40 is for each monthly billing period! I am still awaiting an explanation from the O2 complaint service. I was otld they would deal with my complaint in 3 days!

Long story; you can tell I am not best pleased. You should call O2 and make sure you are clear of charges before you go!!! Good luck.

It's easy to avoid charges if you follow our advice and ask questions before you go.
A persons lack of understanding is not grounds for complaint when all the info is readily available on forum or o2 website.

Simply turning off mobile/cellular data will prevent any charges at all. Do it preferably just before you board the flight.

So I flew to the USA Friday then to the Caribbean Saturday 

I put the iPhone into airplane mode before leaving the uk and only turned wifi back on on the plane.

used the paid for service for data in jfk and used tugo for all texts etc

flew to st marrteen Saturday and was without wifi for a bit turned airplane mode off turned mobile data off made 1 very quick call back home to say arrived ok . Then airplane mode .

looking at myO2 this morning no charges at all showing .

So it shows it works will check again in on Tuesday morning to see if my call charge shows up .

I made 2 calls to my bank last week to get my cards unblocked, 25 minutes and 28 minutes. No charges and a saving of £105.00. Call quality excellent though I had very good wifi

And proof @adamtemp64 that TuGo DOES work (occasionally) with iPhones...
