How do I remove a SIM Card from a Nexus 6 without the proper Sim removal tool?


I would not use a needle, but a straightened out paperclip has been a long time friend to the sim card removers out there. You might need to find a thin paper clip, but a needle could be a dangerous choice.

I am using nokia 5130 .but it was some problem,some times my mobile showing sim card regestration failed


Perhaps there is some loose connection of the SIM card to the SIM card holder and contacts. So remove the battery and the SIM card., Use a paper to polish the SIM card contacts and the contacts on the holder. Make sure that the SIM when placed fits well into the holder firmly and in place , If not you can lift up the contacts very carefully so that the SIM never loses contact.
If this wont solve there are errors in the main board which might need more attention with help from Nokia care.

How and where can I put in simcard to my iphone 3G. I can't find any tool. Several people on the internett suggest to use a needle, but is this advice smart and do it work?


The SIM card tray (long oval shape cover) is located next to the headphone port. Right next to it is a tiny hole. Straighten out a paper clip (paper clip seems to do the job quite well, however any thin rigid "tool" will do); insert the paper clip into the hole and pop open the SIM card tray. As long as you don't use excess force to pop open the tray, you will not damage your phone.

What is the meaning of cdma? is it normal sim card


In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access(CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs.

Put in sim aske a code wrong then contact operator popped up ?


When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

There is no instructions as to how to open the phone to insert the SIM card. I have looked around the phone, I can't see how to put the card in. The accompanying papers have no instruction as to how to do...


Next to your headphone port which is the big hole at the top of your iphone there is a tiny hole, youll need a needle or something tiny with a pointy end and then stick it into the tiny hole and then the sim card tray pushes itself out. Then place your sim card in it and push the sim card tray back in. Its that simple! Hope this helps.

Thanks

Insert sim


Hi have a repair shop, and you know it’s a very common problem on this model. 90% of the cases I found liquid damage in the phone damaging the Sim Ic, it’s a little square one near your sim reader, you can also clean around that with a soft tooth brush and mentholated sprits. Don’t fiddle with your sin contact/ reader if no damage visible to the eye.

In most cases putting in your sim card will in fact lock the phone. but it's not permanent. So try it. put your sim card in.. if the phone works, then you don't have to worry about unlocking it. If it does lock the phone, just put back his sim into the phone and it will be fine. There are many places that you can unlock phones or even purchase unlock codes. This is NOT illegal, phone carriers just make it difficult to do. Good luck and let me know of the results.
