Is Xperia Z2 support 2G Sim cards?

[PeymanLasemi]

I trimmed sim.but this sim working correctly in Z1

Im sure the Apn settings are correct

[Uliwooly]

now that's quite odd, what if you re-enter the APN settings manually? 

[PeymanLasemi]

Im do that!

I Contact with the operator and they send the settings for me but the same result

[Uliwooly]

which carrier/network do you have? and which version of the Z2 do you have?

[PeymanLasemi]

Mobile network(gsm)2G
D6503 with the latest update.314

Should not cause this issue but if your SIM only supports GSM, make sure you have selected GSM only under Settings -> More -> Mobile networks -> Network mode.
Could you try a real microSIM as well?

[PeymanLasemi]

Its set to GSM
I cant acces the real micro sim card.i tried 3g sim but it seems no problem
Why my sim works without problem in Z1?
When i turn off data it works good but when i have a call its freezing again

[Rickard]

What if you try your phone with the 3G SIM and have your phone set to GSM only? If that works i suggest that you contact your operator to get a proper micro SIM.
Not sure why it works in your Z1 but if you have a worn or damaged SIM it may or may not work when you try it in different phones.

[PeymanLasemi]

With 3G it set to wcdma only
I though that my sim damaged i took new sim with new version but no difference

i have the exact same problem...please can you figure out a solution,,,as if it is a software problem or a sim card problem or the device problem itself.
