Although giffgaff has had outages in the year and half ive been with them, I cant moan, a flood, an o2 problem etc... They often communicate better via their website then the big companies.
As for value for money, £10 a month for 250 mins, unlimited txt and data of 1gb or £12 for unlimited data. Biggest advantage now is tethering is allowed on the £10 package which is perfect for me.
Either way you have nothing to lose trying giffgaff, you can transfer your mobile number (and choose the day) and if you don't like it your not stuck in a contract and can move on.! All my family and friends have moved over as we all try to save money and now all calls to family are free so 250 minutes last without any issues and with imessage / whatsapp if your near a wifi theres always a backup communication.
Shameless plug time, use the below address to order a sim with £5 on it if my review was of use.
thanks for reading my review :)
