In fact,the modem were not unlocked,but the DC-unlocker alwasy tell me they were unlocked
I tried several times,

We see few E660 modems with same problem, modem accept code (your modem unlock code 50318703) , but not unlocks. You can try enter this code with mobile partner, probably result will same. Maybe try search firmware upgrade ?
