Xperia M Dual SIM card issue

[arunsa]

Hi
I recently purchased a Xperia M Dual Sim model. Unfortunately I did not know that it was a micro SIM. Now I already have a Nokia Lumia 520 with Micro SIM. The one in Lumia was cut locally by mobile salesaman. The dimensions of the micro SIM was not exactly as per specifications with it looking more like a Nano SIM with all the plastic edges trimmed out. Now this one works fine in LUMIA but as I insert them in Xperia M , it gives error NO SIM.I have carefully seen that the 6 connector points in SIM matches with the 6 quadrants in the SIM but no avail and tried multiple times in both the SIM slots of this dual SIM model. When I look carefully I see that the SIM slots in xperia may have a switch mechanism in the bottom of their SIM slot which detects SIMs which are not cut properly or are not of the perfect dimensions. Is it true for any of the guys over here. Pls help cos otherwise Id have to thing that there is a defect in the SIM SloT which is doubt as none of the SIM slots seem to recognize the all trimmed SIM card.I have checked in both the slots and they are the same.
Thanks
Saboo

Thanks Ajit ,

Actually I am amused that my query led to so much heat here. Actually Today I got myself a replacement micro SIM. and well my suspision was right.There is a small golden coloured triangular switch which bends and makes contact only when a micro SIM with perfect dimensions is fitted there. Well Xperia M has been a very attractive device so far except with the SIM issue. No offence to my dear Sony Support fellow but why cant all the mobile devices be as simple as Nokia.

Thanks a lot anyways

Hi..I have bought a new experia m dual simply model no. C2004. I am unable to connect to Internet using BSNL 3g despite downloading Internet settings and getting help from bsnl customer care. It says check your network settings. I have tried using it in both the sim ports. Although I can connect to Vodafone Internet in any of the ports. please assist.

I also have faced network problems when used bsnl 3G sim. The same bsnl sim gives full 3G network and great internet speed when used in alcatel one touch 919N a very old and cheap mobile of 2011. while other sims work without problems on this xperia m dual. Seems like there is a problem of baseband in xperia m dual which makes this awesome mobile a bad choice at 3G bsnl. But network and 3G speed is good when I go on terrace using bsnl 3G. When used alcatel OT 918N mob with bsnl 3G then no need to go on terrace.
