I brought Huawei E8231 before 1 year.Still it is working good.
3G speed of this modem is best.but 2g speed is not good.
In vodafone 2G network, my old Nokia C6 is giving 291kbps speed but wingle is giving only 170 kbps.Max 2g speed 237kbps which is giving by only idea whose sim is well working with this wingle.
But in case of 3g all sim are giving best speed.i am missing 4G with this wingle.
Problem:
1)Modem is connected with network but not give any data connection.
2)Disconnection problem.
3)In network selection, only 3G mode is not given.
4)More important, In setting I need to give user name and password in 2 minute interval which is annoying me.That is why I will not recommend this product to you.
