Well, some days ago, I've blamed the U.S. carrriers for not offering any prepaid data enabled SIMs for inbound roamers and it turns out, I was wrong. Well, it wasn't just me who was wrong but basically the sales person at AT&T had no clue what he is selling. My fellow MVP and friend Mike Temporale just told me 2 days ago that he is using an AT&T SIM card if he is in the U.S. and that this SIM works perfect for data as well.
As you might can imagine, I was somewhat irritated but he showed me and indeed he was accessing Smartphone Thoughts without any problems, straight from his Windows Mobile smartphone. Furthermore he told me that it doesn't matters which plan you use, either the US$ 100 for one year or the US$ 0.25 per day, both would work.
Since the MVP Summit ended today and I have some time, I've decided to visit AT&T again, not asking for a data enabled SIM card but just picking a prepaid SIM straight and after I've figured out which APN I have to use, I made it working. You have to use AT&T's MEdia Net APN and ev2en if this is said to be an WAP APN only, it works fine. I already got HTTP, POP3, IMAP4, Windows Live Messenger and even Remote Terminal Client and my SlingBox working. Basically every Internet service works, even if Web/Port 80 traffic goes through AT&T's proxy server.
So I'm currently sitting in one of my favorite Starbucks here in downtown Seattle, enjoying a fresh coffe and writing this posting from my HTC Shift. Since I will be back in the U.S., the invest wasn't that bad, even if I bought it 4 days later then initially planned. Man, that sucks if sale guys don't know what they are selling. Maybe someone in charge of sales read this? Hopefully someone does and tells the salesguys on the next sales meeting that visitors are a serious revenue stream they shouldn't give wrong information! At least I've paid US$ 100 in advance which isn't a bad ARPU anyway.
