Interestingly enough, our callers had no apparent issues on their end of the line comprehending our distinctive voices, but the same cannot be said about the experience on our side. Surprisingly, the earpiece produces some crackly and muffled voices that don’t necessarily provide the most audible calling experience. Moreover, the same experience is evident with the handset’s speakerphone as well – which renders it almost incapable of carrying out a lengthy conversation.

Riding steadily at -77 dBm of signal strength in high coverage areas, we didn’t experience any abrupt movements during our testing – nor did it drop any calls as well in the greater Philadelphia region.

Even though we managed to pull through a solid 8 hour work shift without the need to charge the handset one bit, we’re rather unimpressed with its battery life. After charging it fully, we rigorously used the Sidekick 4G and managed to reach the 10 hour mark before it tapped out completely. Considering that it’s a messaging oriented device, you’ll probably want to consider juicing it up whenever possible to avoid finding yourself phoneless.


Rising back from a shallow grave, the T-Mobile Sidekick 4G has enough fuel in its tank to supremely live up the expectations brought on by previous devices. Still embodying and placing a lot of attention on some of its beloved prime features, there’s no denying that this modernized Sidekick will undoubtedly keep up with the demanding needs of the no talk and all messaging personalities of today’s youth. At $99.99 on-contract, the T-Mobile Sidekick 4G has plenty of admirable features and specs to keep its head above water against some of the competition. Granted that it isn’t the best looking Sidekick we’ve seen, we’re more than pleased with the drastically customized Android experience and its bevy of messaging oriented services that are no doubt appreciable on so many levels.

Software version of the reviewed unit: Android 2.2.1, Build FROYOO.UVKD1
