hello.. Today i just bought an Sony Xperia M4 Aqua E2363 Dual SIM, so is just brand new no rooted or installed some application by me, but i'm facing a problem with connecting to the network (T-Mobile is my operator), when i put the nano-sim inside goes reset which is normally.. but then says that there's no Service and only Emergency Calls.. i tried turn off/on.. re-inserting the sim card.. plane mode on/off nothing so far. Also when i go to search networks is listed all the networks.. when i choose T-Mobile.. is always coming with a message ''Could not connect to network now. Please try again later''. So if someone can give me some hints i'll be very grateful.. is the software or maybe phone problem ? Thanks
