Unlocking ZTE Android Z820 without data loss.

Question

How do I unlock ZTE Android phone z820 without losing data/phone information?

Answer 1

There are two ways you can unlock an Android phone without damaging or deleting the data stored on it:

1. Contact a local phone service or local ZTE representatives and they should unlock it for a small fee or for free, depends entirely if you have a contract or not.

2. Actually entering the unlock data: PIN, pattern, email verification, etc.

I recommend trying the second method because is the safest one around, but if that doesn't work, visit a local phone service shop and they should do it for a small fee.
