Sick and tired of searching for that elusive modem ? Search post #2 for I9300 modems & post #3 for the I9300T variant.
All modems are interchangeable between both these models. The I9300T modem is optimised for the 850 MHz band, but it may not be the best for you. Try, test and find out
I do encourage members to post their recommended modems for their various region / location / carrier / device model and testing results (signal strength & stability, speed, call quality, battery life etc).
However, please do not turn this into “which is the best modem for.........” thread. In most cases it is subjective. Your carrier, topography, location, time of day / night, network congestion, and distance from cell tower etc all make huge difference. Try, test them for yourself, and then post
If you have a modem or request for a missing I9300 or I9300T, please feel free to post here and I’ll add it to OP (credit given) or endeavour to source and package it for you as soon as I’m able.
