While several other North American carriers are tossing around tales of LTE development and blazing 4G speeds, T-Mobile looks to be preparing its first entry into the realm of 3G USB modems. No matter though, T-Mobile’s 3G network is so young we’d probably fall off our seats if the company started talking about 4G beyond the stock “yeah, we’re working on it” it already handed out last year. According to a purported screen shot of T-Mobile’s internal system, the webConnect USB Laptop Stick will finally see the light of day on March 25th. It will be rated perfectly in line with AT&T and Verizon, running $59.99 per month for 3G, EDGE and HotSpot connectivity with a cellular data cap set at 5 GB. T-Mobile’s software will automatically choose the best available network on the fly which is nice, but if you move around a lot expect to be using one of the latter in most areas. The last caveat is that these modems will only be available to customers already holding a T-Mobile account. We would hardly consider that a big deal of course — if you’re using another carrier for cell service are you really going to opt for a younger, much smaller data network when choosing a USB stick? We love us some T-Mobile, but it still has a long way to go before its 3G network can compete.
