Please don't buy Huawei ones everytime you change your Sim card to another phone you have to run to a cell outlet to download WhatsApp again and the Reps don't even carry a phone to assist you I came to vodacom they have a rep there who says he don't have a phone to assist me must wait thill Thursday this happens everytime I change my phone I would like to tell the community not to invest in Huawei phones because they are **** with **** service
