3G USIM in 2.5G pda

I am tempted to go for the orange spv m2000 -although it costs more than the MDAIII- if I can use it with my orange 3G usim where I've got lots of free data allowance. Alternatively, I would go for TMobile but I would have to take one of these expensive data bundles.
Has anyone tried to use the SPV M2000, or the xda2s or the MDA III with a 3G SIM card from the same operator? Does it work?
I've read 2.5G phones would not accept 3G usim cards, but I spent the past couple of weeks in Canada where I used my Orange 3G USIM card in an unlocked Vodafone-branded Nokia 6600... and it worked great!
Any help would be much appreciated.
There is no reason why a 3G sim can't work in any 2G phone. Of course you will only get GSM/GPRS and not 3G services. I've used one in various xda's and no problems at all.
Having said that I have heard reports that sims from the '3' network don't work in xda's. Dont know if thats true.
Great
That's great, many thanks.
Are you happy with your xda? Is that the O2 one? Are you allowed to browse outside O2 active? and how much are you charged for gprs browsing?
cheers

HTC UNI PROBLEMS WITH RECEPTION IN INDIA

hi all,
i've had the uni for a couple of months now & i use Hutch service..
i've had quite a few complaints from people who call me that the voice breas up when i talk to them..
the signal shows full reception as i mostly use my phone in office...
i used to use the mini at the same place & never had a problem with reception...
i'm using the latest o2 rom on the exec...
i have been told that quite a few uni users in india have the same problem..
a frien is using the i-mate rom & he too has the same problem....
any help??
Regards,
frz
anybody???
I'm in thane.... using Airtel. Have had no issues with network reception with the Uni. Have u accidently set the phone band to PCS 1900?
If one switches to PCS 1900 then the handset will never search for Netwrok.There could b issue with the internal antenna.Search the forum, how to fix the antena for better reception or go to the nearest service center to fix the issue.
Me too, using JASJAR on Airtel more than a year...no such serious issues
I am also using Universal on Airtel Network without anyproblems.
Hi, check out my experience, I think you are suffering the same thing I did:
http://forum.xda-developers.com/viewtopic.php?t=34920&highlight=faulty
The best way is to get a complete GSM antenna like I did.
Best regards!

Are you sure its a GSM network? As far as I know, the galaxy s is incompatible with cdma networks. I could be wrong tho.

Movistar in Spain uses GSM, not CDMA, but the bands are not the same for 3G, that'e your problem. You won't get 3G on Europe, only in the US with AT&T, Canada with almost any carrier, and any country from Mexico to Argentina.
Maybe in Australia/India you can have 3G, I don't know, but there are some members with a Glide from India, they can answer this better than me.
Thank you, I'm stupid, I should havechecked that before buying the phone

On the samsung galaxy s captivate it says:
Network Technology EDGE, GSM, HSDPA, UMTS
Does that change anything?

I think I may have good news for you, check this:

There's a good chance you have to set the APN settings manually, the above link shows you how to do this. These are the settings that tell your phone how to get onto the data network, if those are not already in the phone or set automatically. Give it a try, your problem has occurred more often and this was the solution!
Setting the APN manually should get internet working, but since the phone doesn't support the bands needed for 3G in Spain, that won't solve the 2G only problem. Still, working 2G data should make it at least fairly usable until you acquire a phone that supports your local bands.
Perhaps not in Spain then, but it works elsewhere in Europe. I live in The Netherlands and I get 3G. Haven't looked into the frequency bands, but it all works perfectly here. There are several other European users here, and I've never read anything about not having 3G because of frequency band issues.
