H2O Wireless launched LTE service yesterday, the first questions on many potential customers minds were "Is it throttled?" and "How fast is it?" That's because although LTE typically achieves speeds of 10 of 100 Mbps, some prepaid operators throttle high speed data to a much lower speed. AT&T's Cricket caps LTE speeds at 8 Mbps and and Page Plus and Straight Talk's Verizon based services limit LTE to just 5 Mbps.
It's too early to be certain but it looks like H2O's LTE is not throttled. A HowardForums member has posted a speed test using H2O LTE that shows a ping of 172 ms and speeds of 28.44 Mbps down and 8.6 Mbps up. The ping is high but the speeds are good. Of course, a single test is not good indication of average speed and ping time but it does appear that H2O's LTE speeds, unlike those of Cricket, Page Plus and Straight Talk Verizon, are not throttled.
It also looks like not just monthly plans but also H2O's Pay As You Go plans are getting LTE. There's no mention of LTE on the Pay As You Go plan's description pages, suggesting that it's only available on monthly plans, but if you purchase an H2O SIM as a new customer there's a drop down where you have to choose a plan. Available plans include "$10 Pay As You Go LTE Plan", "$20 Pay As You Go LTE Plan", "$25 Pay As You Go LTE Plan", "$30 Pay As You Go LTE Plan" and "$100 Pay As You Go LTE Plan". It will be interesting to see what sort of LTE speeds the Pay As You Go plans get as up to now H2O Pay As You Go HSPA+ 4G speeds have been throttled to about 1 Mbps.
Update 1/14: A reader (thanks Alfredo) shared the new APN settings for H2O LTE:
APN - PRODATA
MMSC - http://mmsc.mobile.att.net
MMS proxy - proxy.mobile.att.net
MMS port - 80
MCC - 310
MNC - 410
Authentication Type - None
APN type - default,mms,supl
APN protocol - IPv4
Bearer - Unspecified
If you're an H2O customer with an LTE capable phone it might be worth changing the APN to PRODATA to see if you get LTE without changing the SIM. I'm a little skeptical about H2O's claim that a new SIM is required.
