F698 flying dual sim phone showing ''invalid sim''


Your phone is a Dual Band, it only works with 900/1800mhz. Make sure that the Sim install in the second Sim slot work for these bands here. Other wise it won't work. Another problem could be the imei number, most of the time it can be resolve by changing the imei number for the second Sim slot, but is kind of hard.
