Do not trust!
I've given my IMEI of my Huawei router to receive the unlock code... I've paid via Paypal the amount of that service (7.70€). I didn't receive any CODE or any confirmations from the seller. I've tried to contact the seller from the e-mail... Didn't receive any reply. I don't think the website is legit... 48h and didn't get any news... I've opened a Paypal dispute to get my money back...
