Xiaomi Mi3 - Broken SIM slot


Hi guys,

How many pins you guys have broken?

My methodology can be applied to all the pins, however I have broken only one pin, so it was more easy to do this operation than if it would be with all the pins.

OK I have 3 pins broken. Can you tell us how?
 
Hi. I had the same problem with the SIM slot, some of the contact pins got broken when removing the tray. I bought a card reader holder connector and a friend of mine who's experienced in welding small hardware parts, manage to weld the connector very carefully and using a special welding iron and lots of patience and a microscope. The hardest part of this process was to unweld and weld again the metalic cover of the SIM slot because it's very close to the components that could melt in a second.
After this I can happily say that my Xiaomi is fully working but I only advise you to try this "surgery" at home if you have lots experience and steady hands. I will leave some links to help:

(this connector is a Nokia connector but it's exactly the same as the Xiaomi mi3)

I have the same problem, they replaced with iphone 3g's sim connector, it works fine...
Thanks. I have bought the replacement for nokia 920 (the one IRS give the link on ebay) and 1 for iphone 3g.
If the first isn't working, I'll retry with the iphone 3g connector.
 
Micro Sim adapters are very bad avoid them I've almost broken a few phones with them. Its worth it just to get a new Sim card.

I know, whats the real problem. If you use the sim tray with the micro sim adapter, than you can broke the pins, if no simcard is insert. Also with this one:

So, becareful and use it just when a simcard is in.
 
Ugh. It seems I broke the SIM card tray just by replacing SIMs, with the micor SIM properly in the adaptor. Not an empty adaptor, no, the micro SIM was properly inserted and taken out. Very disappointed, @ibuygou is not responding...

I don't have the expertise to do this repair myself here in London, very nervous.

Sono riuscito a riparare il mio MI3 senza rimuovere il supporto di metallo. Se siete interessati a sapere come, basta dire. [/ Quote]

Sono interessato a riparare due perni nella slot della scheda sim del MI3 Xiaomi senza rimuovere il supporto metallico. Tu mi spieghi come fare? Grazie.

[Quote = "FJ !!, posta: 220.965, membro: 110482"] Ugh. Sembra che ho rotto il vassoio carta SIM semplicemente sostituendo SIM, con la micor SIM correttamente l'adattatore. Non un adattatore vuoto, no, la micro SIM è stata inserita correttamente e portato fuori. Molto deluso,ibuygou non risponde ...

Non ho le competenze per fare questo io stesso riparare qui a Londra, molto nervoso. [/ Quote]

Open the phone with a proper kit is easy. See the links in this blog. Buy the sim card slot is easy on ebay just search for: sim card slot for nokia 920 or nokia 1020 .. it is the same as that of the xiaoi MI3. Find a service center for the replacement of the slot.
