Jiayu G5 Network Issues

[Pilot300]

Hi, I am new here and from the UK not France but I cannot find any English forums for the G5.

 

I have had my G5 now for about 1 week. My main network provider is T-mobile which only uses WCDMA 2100MHZ and my second Sim card is O2 that uses WCDMA 900 and 2100.

 

The O2 Sim card works perfectly ok. But the T-mobile sim card keeps dropping signal. When it shows signal it will not make a phone call. It keeps dropping 3G connectivity. This can happen once an hour or once a day. The only way to fix this is to take the sim card out and put back in.

 

I do get a 3g connection though on both Sim car slots. but the advert says i should only get it on sim 1.

 

Can anyone help me please?

The only problem i get with sim card is the phone around 6/7 times by day say the sim card is not present .. after 2 seconds sim card are detected again...

only slot 1 (SIM 1) is available for WCDMA network

SIM2 can receive only GSM frequencies

 

so you can't use WCDMA network (3G) both SIM1 ans SIM2... and do not forget that the Jiayu G5 is not compatible with the WCDMA 900mhz frequency, only 2100 Mhz

 

majority af chinese smartphone works similary : SIM1 2G+3G / SIM2 only 2G
