Soon after the unlocking of H3G Tre Italy E3131 (E3131S-2) modem, finally I got the solution for unlocking of Airtel Nigeria E3131 Huawei 4G dongle. Unlocking process of the Nigerian E3131 is also same, as it also comes with un-customized firmware, and there is bulky process involved.

Note : Don’t use any wrong / free codes into E3131 Huawei (Airtel Nigeria) 4G data card. It comes with Huawei new algorithm security and can not be unlocked with old algorithm security unlock code. If you will try with wrong codes then your modem will be locked permanently. Pay 2.38 USD through PayPal button of this site and mention model with IMEI in transaction.


Note : I provides the Huawei wifi mifi routers / gateway unlock codes also in cheap rates.
