I upgraded to a samsung note 3. This was via the internet due to difficulties getting to the shop. It arrived late monday by the tuesday i noticed it kept going on to emergency calls only. I went to my local shop the next day trying sat nav etc and it kept losing signal. The shop tried my sim and said it was ok and to contact o2 they also checked the settings and changed the sim. I have chatted to o2 many times being cut off etc. I am partially deaf so calls are hard. I have had the settings checked a further 2 times nut it still cuts out for no reason. Today i spoke customer services who wanted to repair it but its only two weeks old and i have been asking about it at the shops and on line since day 3. They have told me to sell it if i dont like it but i will lose out financially then. Any suggestions. I explained i need my emails and sat nav hence choosing this phone, i dont want to be without a phone and i dont have one to use that can offer these. Plus not keen paying 600 for a repaired phone when still 2 years less 2 weeks to go
