Change to a telecom iphone5, Fetion registered the previous mobile phone number, but I found that Fetion sent to me by others often failed to receive it.

Because your phone number bound by Fetion is still the previous phone number, when your telecom phone is not logged in to Fetion, the Fetion message sent by your friend will be sent to your phone number by default in the form of Fetion SMS.

If your telecom mobile phone logs in to Mobile Fetion, it is your client's online reception.

I suggest you change the bound mobile phone number. Now Mobile Fetion can bind the mobile phone numbers of Unicom and Telecom, so that when your friends send you a Fetion again, you will receive a Fetion by SMS.

If in doubt, please contact 10086 for details.

Have a nice day, China Mobile.
