Samsung Galaxy Note 3: How to Unlock SIM for Free

Galaxy Note 3 users who wish to unlock their SIM, which is locked to a particular network, may follow our step-by-step guide. The tutorial offers two methods: one is to unlock the Note 3 SIM for free and the other to buy an unlock code from any site specialising in unlocking SIM.

Unlocking the Note 3 SIM will help users to switch between carriers and buy local SIM cards while travelling to avoid roaming fees. Besides, unlocking does not require rooting, installing kernel or custom builds.

The SIM unlock method will not work for all networks as they could be using different GSM bands all of which may not be compatible with the Note 3 model. Verify the bands (2G/3G or, 4G), which the smartphone supports before following the unlock guide.
