IPhone 5 Three Network problems?

I need help with my iPhone 5 on the Three network. I have a PAYG Sim but I have the Add-On 'All-in One 15'. This give me 300 minutes, 3000 texts and 'All-you-can-eat data' for £15 a month. But for some reason my Internet has just played up. I've had this phone since Christmas, and it has been perfectly fine the previous months. I checked on the My3 account and it says everything is fine. Except, it just isn't. It works sometimes, but on things such as KIK, Facebook, Twitter etc. It has just started playing up.
Could someone give me advice please? I've tried rebooting the phone/taking the SIM card out but it just doesn't work.

If anybody has any advice which could help, I would be extremely grateful

Could it be a problem in your area (signal etc)

If i where you I would ring up 3 Customer services and tell them about your problem and see what they can do

I'm on 3network and buy the same add on as you -) i'm down in the south of england, and mines fine. Only thing i can suggest is go onto the 3 website and you can check coverage in your area and also you can check to see if they are having problems with the mobile internet.other than that i would say call them or pop into a 3 shop.

  • Wi-Fi on iPhone keeps saying unable to join network (my network name)? How can I fix this! It's been like this for a week but it works on my laptop fine. I tried unplugging it for a few seconds, I tried resetting network settings, I tried turning my phone off then on again, and I know I'm typing it right. I even typed it in upper case AND lower case. Does anyone know how I can fix this?
  • What's the difference between off-network and on-network? I'm try to work out which is best for what I want out of the service. I want protection while on my iPhone 5 (both when connected via Wi-Fi and when roaming on 3/4G). Website with product details: http://www.umbrella.com/products/umbrella-security-features/
  • Not receiving notifications or able to enter some apps on my iphone because network problems? Recently, i haven't been able to go into some apps due to network issues. At moments, I'm able to. I can go to safari and it can go slow or normally. I've taken the plug out of the router and placed it back in, turned off my Wi-Fi connection on the iphone. I don't know what do do… When i was connected to the Wi-Fi at my school, everything went normally--received notifications and was able to msg as normal.
  • My iphone will not connect to my home Wi-Fi. It can connect to any other network with no problems All my other devices at home connect with no problem, but once i updated my phone it won't connect here. I've reset the router, my network settings, forgot this network, even wiped out my phone and it still won't work. I changed the dns several times. Sometimes that works for a little while, but then eventually stops. What the hell?
