PUK can’t be given like this. You have to contact the zain support center. They have your sim PUK. & give to tou

Hi, to get the Puk code to unlock your phone,you will have to contact service provider which is specific for each mobile number.

Puk code does not affect the phone your using,but it affects the Sim card and it unables you to make out going calls. And you will not have access to thing on your Sim card.

To get your Puk code for you Sim card,you can contact service provider located in your area for help.
You can go to any of your service provider outlet stores around your area.Or you can contact them through customer care line..Am sure you know their phone number to contact them.

You can not get a Puk code to unlock your phone from another source except through your service provider service..

Take care

This one issue that you might encounter using a China phone. Some times the usual settings that the Wireless companies use does not work on this kind of phone. This might be due to incompatible hardware or software running on the phone.

You can check if the China phone's manufacturer has a web site. They might have a support link. But not all have this. Or check with Zain if they were able to get their service to work before with this brand and model.

Usually, mms has settings like gprs. Therefore these settings needs to be set on your phone by your Internet service provider, on request.

In my country, mms and gprs phone setting are usually sent automatically by internet service providers immediately you insert your sim card into a phone that has mms & gprs. And these internet service providers are also the network providers.

For instance, if your network provider is Zain, MMS & GPRS settings must be from Zain because that's the network you are using. These settings are as follows: IP Adress (eg. 172.018.254.005), homepage (e.g wap.uk.zain.com), port (1902) and so on....

So check if the above are intact on your phone as this is the only thing that can make your mms work.
Go to message, under message, look out for mms settings and you will see what I am talking about.

Take care.

you could try a master reset, setting the phones software back to the start. One thing this deleted all of you personal stuff if done right.
good luck
