"I bought a Xperia Z3 Plus About 2 weeks ago I had to send it back as the camera was faulty.
I have received the replacement today But it has arrived with a new SIM Pack. I also have an email worded the same as my first order. It is worded in a way that suggests payment for the handset was taken again. I'm assuming that isn't the case.
But the Main issue Is that I like the number I received With the telephone And I have passed on this telephone number To my new employer And would like to keep that number But because I have been sent a new SIM I'm not sure which sim I should be using?
Can I just go ahead and put the old SIM into the new phone and continue with my allowance?
Or am I expected to use the new sim?"
I got lots of answers saying not to worry just put the old sim in. I did that and giffgaff came on screen and I had 4 bars of reception... I proceed to set everything up on my new phone assuming the network side of things was OK. however I've just try to send a text and make a telephone call and neither are working the text just fails and calls don't connect they fail too.
