If you need to get the unlock code for the Samsung M310, the carrier can send you the unlocking code FREE, but you must meet certain requirements, you must be the device´s owner and the contract must be finished. We know that sometimes it is complicated to fulfill this, if you have a second-hand phone or live in other country, get the unlocking code can be an impossible task, but do not worry! our Samsung servers can calculate the official unlock code in a few minutes or hours; we send you the unlocking steps by email.
Turn on the M310 with an unaccepted SIM card (different than the one in which the phone works)and the device will request the unlock code; sometimes is necessary the unfreeze code MCK (if the attempts are exhausted phone required SIM network PIN blocked. Enter SIM network PUK) other times you will need the regional code RGCK (if you are going to use the mobile in another continent or region), in our company we also provide these unlocking codes.
Yes, of course, the unlocking is never removed, you can update as many times as you want your device or even reset the phone.
You can use the Samsung with any SIM Card from Australia and from overseas, such as service providers 3 Hutchison, Crazy John's, Globalstar, One. Tel, Optus, Virgin, Vodafone
Most mobile phones bought under contract from a carrier are blocked. It means that your M310 can only receive signal from only this carrier. If you insert a SIM card from a different network providers, the phone will request the unlock code, or will show the message; Invalid SIM card.
If the M310 do not make and receive call could be because SIM lock is enable and you need the unlocking code or unlock by Device Unlock app, or could be because the IMEI number is in blacklist, in this case, if you unlock the device with unlock code, you must call to the carrier and fix this problem.
