I've had my Samsung Galaxy S3 for 18 months now and have used Giff Gaff for the whole of that time. When I first got the phone and set everything up (with the instructions I found on here, so thanks to those who provided the info!) the internet reception was fine when roaming about, be it in my city (Cambridge) and around other towns and cities.
Though the past 3-4 months I have struggled to do anything via the internet when I can't connect to a WiFi spot. I've rebooted the phone, made all the changes to the settings and even checked the areas I work in for 3G coverage (which were all fine), yet my phone struggles to send a message via Whatsapp, Facebook message or even a Tweet!
Is it the Samsung phone that's trying to tell me to upgrade as it's slowly starting to stall when using apps that need access to the internet or should I simply change provider and go with one that ensures I have a better coverage?
Please refer me to the best that you can, I'd really appreciate it.
Thanks guys & girls!
