I m swapping networks because I m going abroad but I m struggling. My phone is an unlocked Samsung Galaxy S5. I m moving to the network 3. I ve tried going into the network settings and connecting that way but it only works for about 30 second before it goes back to saying it can t register. I can t make phone calls or send texts. I m spending 3 months away from my family so I need this fixed. Can anyone help me?
Thanks
