Question regarding frequencies

So i'm from Israel, and I bought my HTC Desire in some local store.
On april ill be on a coast-to-coast trip for 3 months in the USA(ohhh yeahhhh) and i was thinking about getting TNT sim card with some data deal, and make my cell phone a wifi-hotspot so i could share the internet connection with my laptop

a friend of mine told me that there are some frequencies differences between Israel and the states, so i was wondering how could i check that my HTC will be able to have internet connection on my trip

TY :)

You will be ok for GSM (2G). I'm not sure what frequency bands are used in Israel, but if they are the European ones you won't get 3g stateside. North America uses different bands for 3G and the Desire comes in different versions for different regions in part because of that.

It won't support all of those protocols on all of those bands.

GSM will be 850/900/1800/1900.

For 3G (WCDMA) the Desire is dual-band. There are 3 versions

  • EU/Asia: 900/2100
  • North America: 850/1900
  • Telestra (Australia): 850/2100
If your phone has 2100 then almost certainly the other 3G band is 900 - given that there's no 850 MHz 3G in Israel, I'd guess that they'd supply the common EU/Asia version rather than the unusual Telestra variant. Have you checked your phone's manual or box for confirmation?

Edit: Don't be too optimistic about the 2100 on T-Mobile USA. That blog states that you need a handset that supports both 1700 and 2100, which no Desire does. I've found another person claim that T-Mob split their upstream/downstream between the 2 bands, which is why you need both. And I found one person posting in a T-Mobile support thread that their UK 3G handset wouldn't work on T-Mobile USA, which supports this statement.

Can I nominate this for "Post of the week"?
 
So the way i see it, i won't be able to use 3G with my Desire

So my new question is: if i want to use my cell as a hotspot for my laptop, will gsm network be adequate, or is gsm really THAT slow? i mean i know in Israel it's kinda slow, just want to know how it's in the states.
Im planning to use my laptop just for internet browsing and perhaps some skype
 
Its (GPRS) between 32 - 48b Kbps so its slower than dial up!. Also you wont be able to receive any calls or anything during this time.
 
Yeah. I dont even bother trying to browse the internet on GPRS. I can just about pull text through to tapatalk and thats not a pleasurable experience. I certainly would not want my computer connecting to the internet on lower than v.34 standard speeds. Thats like 20 years old.
