From day one..whn i gt this handset last year, i had the "not registered on network "error
I noticed that each time i hit n LTE area, the phones data connection would die but still show network signal...try to make a call, phone is dead, no network..
TEMP FIX-under the settings, change from LTE(auto) to wcdma, this worked for me, was able to use the data under 3g connection and have access to the network.
So i took the handset in to the voda walk in cntr..guy did say tht he saw this previously with the LTE version of the s3..sadly, this is a network issue..only fix they could offer was a change of network.
no sim swap will help, no firmware will help aswell, the handset came preloaded with vodacoms settings aswell.
I called vodacom today..only to discover that LTE service was NOT enabled on myline...now the activation is done, will test later this evening and get back to u guys
Quick one-whn looking for a LTE handset on vodacom contracts, the sales person wil try nand give you a normal s3 under the LTE special..so be weary..i called and visited plenty stroes, all advised me that they DID have the 4g handset..but they all lied..so js be carefull
