Hi is your samsung galaxy s3 mini is not accepting your network sim in it whether it is displaying any messages like sim invalid ,sim lock and so on once you insert your sim in it then it mean your phone is locked to some other network provider due to this it wont accept your sim until you unlock it .You can easily unlock your phone through online providers like TheUnlockArena.com here they are rendering network unlock code for all mobile models at reliable cost .You first check that whether the code is available for your country and network provider .If yes then pay for it and unlock your phone then freely use it with any GSM sim ....

Significant Differences between the:
Samsung Galaxy S3 and the S3 Mini:

1. The S3 has all the bells and whistles of being more advanced in hardware and software then the S3 Mini

2. The S3 can last longer in battery life than the S3 Mini

3. The S3 has more storage space available for more apps than the S3 Mini.

4. The S3 is more complex with its many software options than the S3 Mini

The S3 Mini is for the Minimalist who doesn't want all of that, but just cares about having a basic phone with a touch screen that has the flexibility of Android.

The S3 is for the person who plans to use their phone for a multitude of things.. or the person who likes to download a lot of apps, either for gaming, as entertainment for their kids, someone who plans to take a lot of photos, and use it for work. You can do this with the S3 Mini as well, but because of its limitations in speed, on board storage, and battery life.. it won't be able to handle as much as the S3 will be able to do.

You can get the unlock code for your Samsung Samsung Galaxy S3 Mini phone from your Network service provider or any third party online vendors like Mobile-Unlocker.com here you need to specify your country,Network name to which it is locked,IMEI number of your phone.

I think that you have to delete the contact from Contacts where you have saved all your phone numbers.

Check where you went wrong. Caps, or any other little mistake, can cause the computer (on the server side) to reject you.
Also try to find out if the provider has a server error.
