Assalam_o_Alaikum How are you, dear experts or readers.
I have Zong 4G dongle E8372h-153 Version 21.328.62.00.1456
I want to unlock it to use all networks sim in it but I am not able to do this because I have tried very much but can't unlock it. A shopkeeper repair it and now I am able to use All sims of Zong network(Zong Data SIM+Zong Normal SIM+Zong Internet SIM) but I am not able to use other networks sims in it please tell me how can I unlock it. Thanks in Advance.
