GoSmart Mobile brand advertises unlimited voice and messaging and 5 GB of data at "3G" speeds for $45/month. That's $30 less than T-Mobile's $70 Monthly 4G plan which promises unlimited voice and messaging and 5 GB of "4G" data.
Because it's advertised as "3G" rather than the "4G" that T-Mobile labels all its other data plans, we knew from the start that GoSmart Mobile's data would be throttled. But we didn't know how how much. Today one of the first users to actually receive a GoSmart SIM ran speed tests in two locations and reported the results on HowardForums.
According the user, whose handle is jaybeeunix and who uses a Nexus 4:
In a location where he gets 2.6 Mbps with Monthly 4G, he got between 0.8 and 0.9 Mbps with GoSmart.
In an area where he gets 26 Mbps with Monthly 4G, he got between 0.89 Mbps (910 kbs) with GoSmart.
This is just one user but he's using a very capable phone that gets an amazing 26 Mbps unthrottled on T-Mobile. I suspect we will see speeds of about 900 kbps or less everywhere on GoSmart Mobile. And that's not a bad thing. 900 kbps is a solid 3G speed, anything over 236 kbps is too fast to be anything but 3G.
900 kbps is plenty fast enough for video streaming, VOIP and app downloads. It's also generally faster than Sprint's EVDO 3G which has a theoretical top speed of 3.1 Mbps but rarely tops 500 kbps in real world use. That leans credence to my theory the GoSmart Mobile's primary target is Sprint's Boost and Virgin Mobile prepaid brands.
If anyone is using GoSmart Mobile's, $35/month for unlimited voice, messaging and "2G" data plan, please run some speed tests and let us know what you get. I'm guess about 128 kbps but I'm hoping it's faster as 128 is just painfully slow for even basic web browsing, although it's fine for email updates without attachments.
Update: a Prepaid Phone News reader has reported getting speeds of 118 Kbps down. and 185 Kbps up with the $35 plan.
