Have signal but cant do\recieve call and text

[HannahCaramoan]

for sony c6603:I have full signal in my sim using talk and text, but i cant do/recieve text or call it says I dont have signal.
What should I do??I already reset it and my sim is new..
It said no selected network unavailable

[Thommo]

Is your device able to use said network ie: is it unlocked for all networks or if you have travelled is your phone country unlocked

[HannahCaramoan]

hi sir how can I check that sir?When I try to call or text it only said that I dont have network 😓

[Thommo]

Dial *#*#7378423#*#* then open Service info then SIM lock and report the findings

[HannahCaramoan]

Thank u sir for the quick response!!
network 0 network subset 0
service provider 0
corporate 0
sim 0

thats what I saw sir..

[HannahCaramoan]

plus sir I have a color yellow notification ! like that saying no service, selected network unavailable..

[Thommo]

Have you travelled to another country with this phone or is it native to the country you are in

[HannahCaramoan]

is a native country sir i think..

[Thommo]

At a guess your SIM is either faulty or there's an issue with your network or if you are on a contract you have been cut off or if PAYG you have no credit

Hi sir I think all is fine, its not contract and here in Phil, I dont know if they have PayG..I dont think its my sim fault cause its new and I try it to my old phone its ok..Im using Talk and Text sim card..I bought a new one cause my old sim cant read by my sony xperia z..And now, I have signal but cant text and call either recieve..
