o2 due to no signal if you are outside the 28 days? I agree with maxstream - if the coverage map says its good and it isn't then you may have a case but it will depend on the small print in your contract. There are some rural areas where no mobile coverage is good - I can get an orange signal in about a third of my house (vodaphone and O2 are even worse) and getting 3G is about as likely as winning the lottery - its one of the joys of living in the countryside (along with slow broadband and paying through the nose for heating oil !). The best way to try out the recption is to get a free sim from each provider and put 5 or 10 PAYG on it and then see what reception you get before tying yourself into a contract. Once you know which one works (if any) then go for that one. Simple solution to not having a phone upstairs is to get a landline extension put in (or do it yourself) - not very expensive and then you'd have a definite phone that you could rely on. Re: Is it possible to get out of a contract with o2 due to no signal if you are outside the 28 days? My view is that you can only justify ending the contract if the coverage maps say reception is good when it isn't and if, when notified, they don't put things
