I got this phone for my Xmas to replace an older Vodaphone PAYG mobile. I'm now back using the original mobile.
I really don't like this mobile. The touch screen is difficult to use and doesn't appear to hold settings. I'd removed the lock function as I was finding it difficult to unlock the phone. For some reason, after I'd topped up the new mobile, the lock function re-appeared without any input from me. This almost caused me to miss picking up my wife from the local station last evening.
I was sent several texts over the Xmas/New Year period and I also sent out quite a few over the same period. The incoming texts only arrived after I'd switched back to my original mobile. Also, I've now discovered that less than 50% of the texts I'd sent out hadn't been received.
This mobile really isn't worth spending even £20 on. I'm going have it returned to Amazon for a full refund.
