hello to all and thanks in advance x the help you can give me .
I'm from Argentina and a week ago I brought an iPhone 5S model A1530 Singapore .
I am currently using an iPhone 5 with the company Claro Argentina and the truth is that the experience with the team and with the lending company is very good .
My problem is that when I tried to activate my new iPhone 5S with the chip I have on my current iPhone 5 team finishes no stable signal raise , lift something signal and within seconds it goes and stays for a while off duty, then also becomes unstable and within minutes becomes lose and so all the time, I am assuming that is never lift 3G.
I tried the computer with a sim from another company (Movistar Argentina ) and it works perfect and then probe my sim (Claro Argentina ) in another iPhone 5S A1530 and it works perfect too.
Already brobe resetting the network settings and restoring the phone from iTunes zero and the problem persists exactly the same.
They no longer do to try to fix it.
I welcome your impressions and if I can lend a hand to solve the problem as it is very frustrating to have in the bag there an iPhone 5S and could not use.
X Thanks again for your help.
