If you could also try turning your device OFF and take your sim card out, then wait 5 minutes,and turn your device ON again,as this can help in most cases. Also try turning your airplane mode ON and OFF again. Please be aware that the signal checker website is updated hourly, so there may be a current issue that's not showing at the moment,so keep checking the signal checker website over the next few hours or so for any new updates. If the signal checker is showing NO reported issues,can you also perform a manual roam,,which basically is searching for networks on your device. Go to your phone's "settings" and Select mobile network options and Change the Network Selection Mode from Automatic to Manual, and list of available networks will be displayed after a few moments, ( be patient whilst your device starts searching for all the available networks) . Once all the available networks are showing, Select any other network that is not your own network,and After a few moments you will see "No Service" on the display. Now select your home provider(which is O2/giffgaff) network and change the selection back to Automatic,and see if that helps.
Try checking your coverage using the link that matthew40 has provided. Failing this, check your phones' internet settings and try turning it off then on again - it does work occasionally.
Have you just joined giffgaff? Unfortunately some people find that data speeds in their area are really poor. If you can try your phone out in another area and see what difference it makes, then you may be able to determine if it's a localised problem.

I've always said before you totally switch over to giffgaff and transfer your number over and cancel your current Network provider. You should get a giffgaff swim Card and try it out to see how it works in your area. Because there's nothing there to hold you down on to the giffgaff network as there's no contracts. So trial it for a month as see how it goes, if it goes all well then make that transition over to giffgaff and if you don't like it say with your current provider. A lot of people go by what's written on the giffgaff website which show network coverage in their area but let me tell you this is hardly ever correct. So you need to try it out yourself. Doing it this way will save you a lot of time and hassle. So please take this advice on board and you'll be great full for it. Hope I've made some sense to you and helped you out a bit. Thanks for reading this.
Hi,it sounds lightly to be the giffgaff Mobile data congestion (which can differ to O2 ) but check for outages on the network where you are by putting your postcode into the link here http://www.bit.ly/ggservicestatus
Also if you have an unlimited data Goodybag then you could be using more than the norm and giffgaff have started to throttle members now
Where members are using more than their fair share of network resource during the busiest hours, a 300 kilobits per second (kbps) restriction will be introduced for the remainder of that day’s peak period. This speed will ensure that members are able to use the internet, but with less impact on other members.
A peer to peer speed restriction of 100kbps during peak hours will also be introduced for these members.
These additions will be active every day between 3pm and midnight and any speed restrictions will be removed at midnight each day.
