I have a strange problem!
I have an O2 XDA II, (unlocked), original ROM (1.03 USA), which I'm using with a UK Vodafone SIM. This works fine in the UK, however I am currently in the US trying to roam, without any luck. The automatic network selection does not connect to any network. Using manual network selection, I can select the T-mobile network, which it connects to, with good signal strength, but if I try to make or receive a call it does not work. It also loses the connection altogether after a few minutes. (This SIM works fine in the US in my Motorola tri-band phone). However, if I use my wife's US T-mobile SIM in the XDA II instead of mine, it works fine!
Any ideas?? All help would be gratefully appreciated!

phone networks must have agreements to let users roam
Vodafone certainly have a roming agreement with T-mobile in the US - I've been using this SIM in a triband phone in the US for years.
Paul
well are you talking about roaming of grps ?
because there are not as many agreements when it comes to grps as there is when it comes to std phone
No, just roaming GSM voice!

Hi all,
Congrats for the nice forum. I got my MDA compact sim free recently which I used with my Vodafone UK sim card and it worked fine. However I have signed a new contract on 3G UK in Phones4you where I was convinced by the dealer that the sim card can be used to another sim free phone apart from the 3G Nokia 6680 I have taken. It seems that this was not true because when I insert the sim card in the MDA it says "Ivalid Sim Card" and I can't use it now. Do you know any way I could manage my problem? Any advice is appreciated. Thank you very much.
I'm interested in this too. I have considered switching to the 3 network but that fact that you have to use their phones has thus far put me off.

Yes, they have good price plans, but I am really disappointed cause I can't use my MDA. Their sim cards seem to be locked and unfortunately I have no idea whether there is any way to make it suitable to non-3G phones.
The dealer lied.
3 will not allow non 3G phones because it involve cost to them. Three roam to O2's GSM (2G and 2.5G) when you are out of range of the 3 network and that costs them money. If you have a 2.5G phone like the Magician then it will be permanently roamed to O2 and they would make no money from you becasue they would be billed by O2 for your calls.
Don't forget you get a "cooling off" period on these contracts. Might be worth using it.
MDA Compact is not a UMTS phone! :roll: I think it couldn't operate in 3G networks! Correct me if I'm wrong.

Are you sure?! This is very strange! Are you talking about Orange in Israel?! :shock:
Thank you all for the replys, it seems that unfortunately in UK it would be impossible to use 3G card on the MDA. As the 6680 has nothing in common with the MDA I hope my bills to compensate the inconvenience :mrgreen:

Using a non umts phone like the magician to connect to a umts network seems to me a very strange and bad idea.
Wait until next year (not so long) and buy the HTC Hermes or the XDA version : it's a S110 with the features of a QTEK 9100 and umts and wifi and ....

Yeah, an Israeli Orange sim card works OK on my Magician.
of course I couldn't use any 3G services... :roll:
3 is a UMTS-only network. All 3G phones in the UK are dual-mode GSM/UMTS phones.
Because the 3 network does not cover enough of the UK it has an arrangement with O2 so that 3 phones will 'roam' to O2 when out of 3 coverage. When they do this they use O2's GSM network. So, a GSM phone with a 3 USim would be permanently roamed to O2 as I said earlier.
An Orange USim will work in an Orange GSM phone. Orange (in the UK) have a GSM Network and are rolling out a UMTS network. When an Orange phone is out of reach of the Orange UMTS network, it simply uses the Orange GSM network instead. Now if you put a usim into an Orange GSM phone, it simply accesses the Orange GSM network and can't see the UMTS one. Oh and it will be able to use the 2.5G GPRS system as well.
A bit wordy but I think it's clear.
also remember folks thats "3" use a 5volt sim card unlike every other uk network that still use the old 3volt cards.
Hopefully someone could help me here...I'm on a prepay with vodafone australia now, but it seems that i can't connect to GPRS and 3G connection (eventhough the vodafone staff changed my SIM card to a 3G capable). Besides that, the staff told me that i need to be on a plan to be able to use GPRS, is that true ? Thanx for the help...I'm using Dopod 900 now
Hi guys,
I own a 32B HTC Magic (from Vodafone Germany), and have been able to use my Virgin Mobile (Australia) SIM card, but have only 1 issue, I can't seem to get 3G working.
I know I have a 3G capable SIM, because it has been used on a Nokia 6110 Navigator at full HSDPA speeds. I'm curious, is there a strange lock that ensures that I can only access 2G and WLAN networks? Is there a work-around that I need to sort out to get access to 3G?
Thank you
I've got an HTC HD2 Virgin branded from Ebay, It said that it is unlocked. Tried it on T-mobile, O2 and Vodafone.
Only worked on T-Mobile.
When I put O2 or Vodafone sim card, it can't even connect to the network.
Is my device locked??? Or is it faulty? Please help
Even on T-Mobile, it's connected to 3G and HSDPA perfectly, internet browsing is no problem. But Calling and SMS is still not possible.
