Hi,

I've been with 48 since last September- the network constantly drops calls- sometimes 2/3 times a day and 2/3 times a day I will have to enter my sim pin as if it has been turned on and off- any advice?- this is a constant prioblem so much so I'm thinking of leaving 48- I also never have 3g coverage band it's not the phone as another sim works fine.- 

Thanks in advance
