I have an 02 xda exec bought in the UK. I am using it in Jamaica with a local Jamaica C & W sim. The phone is not locked and is currently using radio 1.08. My Jamaica sim has full roaming and works perfectly throughout the caribbean when used in my old Sony p800.
The problem is that when the sim is in the Exec the phone will not switch networks when I am in Trinidad. Works fine within Jamaica but refuses to log onto the Trinidad C & W network
Jamaica has two providers, C & W and Digicel. I am not sure exactly which band each uses but since the p800 is 900/1800/1900 and works fine on both networks they are clearly using bands that the O2 is supposed to recognise. In Jamaica the xda will lock onto C & W or Digicel depending on which sim is inserted but it always requires a manual search to get it to work. During the manual search, only one network at a time is ever found and sometimes it requires multiple tries to get it to recognise the network.
Trinidad has two providers TSTT (part C & W) and Digicel which are again both using one of 900/1800/1900. When I am in Trinidad, the phone will not even try to seek a new network automatically even after the battery is removed. The signal icon goes straight to the ! icon without the moving .... that indicate it is searching. If I try a manual search on any combination of auto/gsm/wcdma and EGSM+DCS1800/PCS1900, the system will find network 374130 but will fail to register. I assume that 374130 is digicel TT.
I have tried this with a Jamaica C&W sim, a Jamaica Digicell sim and a TSTT sim with the same result in every case. I havent been able to try a Trinidad Digicel sim since they are not yet up and running.
Can someone tell me where to find a complete list of networks with their name and band used so that I can confirm that 374130 is Trinidad digicel. More importantly can anyone suggest why the phone wont switch networks when I roam.
Finally, I should point out that the phone also failed to find networks in Antigua, Barbados and Miami, all of which work fine on my p800 with the same sim

I just unlocked my SPV-M5000 and replaced the orange 3G sim with a regular Vodafone SIM. Much to my surprise the phone after a few minutes of being on the regular 2G network picked up the UTMS network from Vodafone (the provider name changed and the gprs symbol changed from G to U).
The coverage was only 2 bars and I could not make calls on it anyway, so I changed my network settings from auto to GSM and now only the 2G network is found. I was wondering how this could have happen when using a regular non 3G sim in the first place.
I think the best thing is to get a 3G sim anyway from Vodafone. Is this something that vodafone would normally do. I would keep the same number etc of course, I just want a 3G sim instead of a 2G one.

I am running an O2 XDA Exec and a Sony Eric 750i.
Have asked O2 to send me a 3G compatable card for the Exec which presumably will be the same number, not sure if this will automatically invalidate the original Sim or if this can continue to be run in my SE?
Any ideas?
Vodafone does not provide any seperate 3G sims. they just provide SIM cards and depending on the phone they are in they pick up the signal.
The o2 3G sims work in all phones......3G or not so I don't think they are any different. They could be.
But as far as Vodafone is concerned, they donot provide seperate SIMs for 3G/2.5G.
There is no such thing as a 3G SIM.
The clever stuff is done by your phone.
Voda and O2 do it differently.
With Voda, any sim will do.
With O2 you need a 3G sim, which are different to a standard 2G sim. I believe this has something to do with enhanced security. Either type of sim will work in a 2G or 3G phone, but of course you can only get a 3G signal with a 3G sim and 3G phone.
Has anyone managed to get there artemis working with a 3g sim card? ie.e the 3 network in the uk? www.three.co.uk? sometimes known as hutchinson 3g?

Not tried it, but UK O2 Orbits are not network locked, you can put any SIM in - although with it not being a 3G device, there seems little point in putting a Three SIM in as it will just drop back to whichever GSM network Three piggybacks on (O2 I think). I'v just bought a three sim for £1.25 on ebay, so I'll load it up and see what the coverage is like near me - I only get intermittent t-mobile in my place...
it used to be possible but then 3 started to locking their sims so they only worked in 3g phones
aha!
im not so fussed about the 3g coverage its more being able to use that sim card in the phone, whethe rit roams off of o2 or etc. i got my phoen unlocked (originally t-mobile compact 3) and its the only simcard that doessnt work - thats why im suspicios of this shop[ who says they can doo it for £50
please keep me updated as to how your simcard goes, and if anyone knows a way of doing this im all ears!
I am visiting India and put in a local SIM card to use with my HD. It cant get a signal at all. I did get the pop up asking to automatically install the new setting for the sim inserted but can't get a signal.
I did a soft reset as well, but no luck. Phone is unlocked so I can't figure out what the issue is. Same SIM card working fine on my 2g iphone.
Any suggestions?
Thanks.
Go to settings --> Select Phone --> Band --> Select auto for network type and gsm band --> soft reset and check settings again to make sure if it is saved to auto.
Let me know the results as i am going to delhi next month.

Hi again,
Now I've managed to unlock my Orange branded OSF and flash the SwedishSpring rom, I've been trying out different UK SIM cards.
Orange and T-Mobile work fine. Problem comes with 2 of the SIM cards I've tried from smaller networks:
TalkMobile - use Vodafone network
Tesco Mobile - use O2 network
For first 5 minutes there is a weak signal and then signal is lost completely only to come back weakly very intermittently.
Going into settings>network providers and trying to connect automatically to a network generates a message saying something like 'the network cannot register this SIM'. There is a list of the big networks (O2, Orange, T-Mobile, Vodafone and 3) and trying to connect to the 'parent' network fails.
The only thing in common with Talk Mobile and Tesco Mobile is that they 'piggyback' onto another network. There is no problem with the Orange and T-Mobile SIMs as I presume being in the list of providers means those SIMs connect without difficulty. The Talk Mobile and Tesco Mobile SIMs presumably try to connect to thier respective 'parent' network and fail once network recognises it isn't an O2 or Vodafone SIM?
The Talk Mobile and Tesco Mobile SIMs work fine in other phones, so not quite sure what's going on. Technical support at Tesco were useless saying, you have unlocked your phone in a non-legitimate way, therefore you can't expect our SIM to work properly (despite the T-Mobile and Orange ones working OK!)
I'm sure one of the tech/gurus/wizards here can provide more useful suggestions and help compared to the Tesco technical support department
Look forward to hearing your thoughts and if anyone else has experienced similar problems and how they solved them.
Thanks
PS. same problem exists even with the original stock Orange ROM prior to flashing FroYo rom.
From what you've mentioned, it sounds like your blade may not be unlocked.
I say this because since Orange & T-mobile merged as Everything Everywhere, their sims can be used to switch on to each others networks on locked devices.
Which method did you use to unlock your blade if I may ask?
I've got my contract EE SIM and Three UK Pay as You GO. When I tried to connect EE with data it connected properly but my Three UK SIM lost the connection. When I switch to data from Three UK it connects and EE still works. Three UK is 3G,4G SIM only mode and it doesn't support GSM. I tried to swap the SIM slots but it doesn't change the situation. Anyone knows the solution?
I'm using this phone on Three UK. The data didn't work at first but that was because mobile data is disabled by default on the stock rom for some reason.
Does the Three sim work for you on it's own? Bizarrely, calls and texts still worked even though the internet didn't even though Three is, as you say, a VOIP only network.
Seems that the update in some way has problem on the radio especially for the 4G : on 4G provider only 3G network is used
did you checked in the engineer mode if some bands haven't been disabled since the last update ? I'm in France using the Orange network and it work on 3g and 4g. Also on the update you have to search for the mobile network once more and select the correct one. I have to say it didn't worked at first for me, switching airplane mode again and again did the trick !

Thanks, nn the engineer mode I have not see any problems, but in the build.prop in the system I have not saw any think related to the LTE network.
No chance I have tried to connect to Orange FR network setting only LTE as band , but the phone could not even to connect to voice network. Other user on the web claim that this happens after the upgrade to the new stock rom
