  4. Hello

    With the new Huawei Mate 10 it gives the option to have both dual sims on 4g network but if you check on Huawei Web site it says they cant both be on 4 G. Sometimes my mms will not download from sim 2 and iam wondering if this is the problem. I ve defaulted to sim 1 for my data but I have them both on 4g because the option is available.. I can visit Huawei service centre store here in Abu Dhabi I guess. Any suggestions. Dual Sim is meant to make life easier it may be something simple I am not activating.

    • Hi,

      The problem is that, Jio offers only 4G network. once you change the data network to airtel your 4G connection will be allotted to the Airtel sim and jio will be converted to 2G network which is unavailable.

      The problem is with the mobile, because most of the handset will support single 4G at a time. When you choose Jio as data network, there will be no issue on Airtel since Airtel has 2G, 3G and 4G networks.

    • Hi Anant,

      Are you using unlimited plans on your airtel number? If you are recharging with a smart plan, then you need to have a talk-time balance in your account.
