Can't make calls

Hi, I've recently got an Xda2 and had all the fun of trying to get it to unlock. having followed all the info on the web and runnung an unlock program on the phone itself, I can insert my SIM, enter the code and all looks fine....but i'm unable to make or receive any calls. Also, I dont sem to be able to find any contacts. Very confused! The SIM works fine in my other phone?? Any words of wisdom would be very welcome at this time,
Many thanks in advance
maybe you could try to use another sim to see if the xda is incompatible with that sim cards it's not unheard off
OK.....this is a bit wierd. I've tried another SIM, still vodafone, but its about 2 years old. It works! Why? Whats the difference between my vodafone SIM and a 2 year old vodafone SIM?
ask vodafone i know that 3 made it so their sims only worked in utms phones maybe vodafone also found a way to block other phones

2 simcards active in one device ?

Hopefully there will be soon smartphone where it will be possible to have 2 simcards online at the same time.
I think lots of people here have the problem taking 2 phones with them (including me)
HTC PLEASE READ THIS !!!
Why do you need to take 2 phones with you. Can't you just forward all calls and data to the other phone??
of course this would be possible BUT ihave to different providers (one for buisness and one private) so that would be very expensive enabling that option.
to have 2 sims active at the same time you will need TWO gsm radio's.
That will make devices (also with limited people asking for it) very expensive.
I do it this way:
1. Dual sim adapter (one sim business, one private) and Wivit SSS.
2. On the private voicemail I mention my business number on which I am reachable during office-hours
Business calls outside office hours end up in voicemail. That fine with me.
Private calls inside office-hours are informed aout my other number, so the caller can try again.
Next to this there are also dual sim adapters that switch every .. minutes from SIM

Dual SIM adaptor

Does anyone know of a dual SIM that fits in and works with Touch Diamond???
Why not use an N-in-1 card that allows you to clone a SIM? I find dual SIM's to decrease battery life on WinMo devices. A Ghost SIM should fit perfectly fine however.
Hi there,
I tried the dual sim adaptors from hot-wire-telekom.
I tried both
the digital:
hot-wire explains that this can cause problems - and it doesnot work
the analog:
should work - but it doesnot
I tried both with a Siemens S55 and it worked (digital version needs a lot of power - only about on third standby left).
I will have to contact the guys from hot-wire to ask what to do with the diamond.
To be continued...

Hmmm interesting... http://www.fonefunshop.co.uk/dualsim/magicsim.htm like this?
Does STK stuff work with winMO 6.1 etc etc.
You sound like you know your stuff so as much info as poss would be super helpful...
many thanks
How about this one from Brando? I'm going to order one soon. It's not cheap($27+3 shipped) though.
It says can directly switch the sim from sim menu.
The STK should work fine in Windows Mobile. DX has them the cheapest and offers free wordwide shipping. I've purchased many things from them and am very happy with their service.

I tried the Magic one and it didn't work. It looks to me that those adaptors work with Nokia type phones only.

Bummer - there must be one that actually works like the 6-in-1 magic SIM
Apparently they can cause problems with 3G/HSDPA? Anyone noticed that?
I almost got one, but having to switch over from one SIM to another and then back to the other just to see if I've missed calls/SMS's etc seems like something that I'd grow tired of very quickly.
If the Diamond had two radios, and could use two SIM's simultaneously, then that would be nice...

Yes I agree - I have put the calls on divert from my Orange number to my 3 sim works a treat problem solved for now - I am seeing a growing trend in Dual Radio phones though. Two HSDPA connections at once... LOL maybe in future we will se channel bonding
Now that would be interesting... It cant be too far off. To be honest, for so many years people have carried two cell phones, (some people more than two!) that I find it kind of strange no-one has tapped that market yet... These SIM adapters are the best attempt at solving the issue, but they just create more issues... I ended up porting my personal number to my work account so I could be done with the whole thing and just have one phone and one number I would have preferred a dual radio phone though!
I have an analog one, which works perfectly. i believe it's the magic sim 1st gen adapter... no problems with hsdpa or anything else
I have one in my Diamond just now, which I previously bought for my iPhone.
I don't know what Generation it is, but its a ghost SIM which you cut your 2 SIM cards and fit into one. I simply turn the celular radio off and on to switch network - either that or reboot the device.
N to 1 sims ?
The problem with all the N to 1 sims (including magicsim) is that you can only clone V1 sim cards (sim cards delivered before 2002 with some countries/operators variations).
Modern sim cards are almost always V2 or V3 versions and for the moment there aren't clonable (august 2008) !!! Trying to clone a V2 or V3 sim card for using a N to 1 sims will in most cases block your sim card defnitively So today the interest of such multisims cards are limited ....
(for myself i had the chance to keep old V1 sim cards and using diamond now with silvercard with sim emu containing two sim clones ....)
I got an answer from hot-wire-telekom for the digital and analog 2-in-1 sim adaptor.
The digital one will not work with PDAs at all.
The analog one should work but there can be problems and the adaptor will not fit perfect. So I should try tape and pieces of paper to make the sim fit in the slot.
I tried it for about one hour and it only worked with one card but did not display the second.
Will take another hour tonight...

Did anyone understand the differences between the three versions (Gold/Black/Silver) ?

Dual Sim 3G compatible for Desire

has anyone used or is using a Dual Sim holder in a HTC Desire, or know of one that works/fits nicely?
I currently tuck an alternative sim between the battery and the back cover but have to take the battery out etc to exchange, would like a simpler solution.
lol same as me mate..i also keep spare 8gb card behind my case too been looking into this apparently it has to be 3g compatble ones- gonna take a punt and try one from ebay-will post a link and let you know results.
apparently some folks are using on nexus 1 so shouldnt be too difficult- also hypercard are selling some at £70(well euros) but not far off. fcuk that gonna look for cheaper alt.
Any news on this dread123 as its something i was thinking about too.
Ive never had any sucess with a dual sim, i just use a super sim in my desire so i can use three sims and dont mess around with any extra bits. Just 1 sim card thats it
http://forum.xda-developers.com/showthread.php?t=714903
check there..got the dual sim working perfect now
hpsda and full 3g speeds..no call dropping ...no problems at all.able to switch from sim toolkit app on phone.
I am using Hypercard V3 which works on 3G too. It only reboots after switching too my vodafone card. Switching from vodafone to O2 no Problem works without reboot. You get a SIM Toolkit Icon on the Home Screen for switching.
Thanks for the replies guys, time to do a bit of reading up

Seems i was given false information, was told super sims dont work on uk sim cards so i gave up on that option.

Dual Sim

Has anyone used this feature? It was one of the reasons I got the phone - I'm planning on moving my landline number to the phone. AT&T said they don't support dual sims (if it works it works, if it doesn't - sorry!). So I thought I'd ask to see if anyone is using dual sims (preferably with AT&T) and how the experience is going .. thanks!

I have two sims in it since day one - works great!
I made this little video of how Dual Sim cards works on this phone:
You can switch data source without taking sims out (in settings)
2 AT&T sims will work just fine - it does not matter who the carrier iss as long as phone can read the sim cards. I use two t-mobile sims. People here have both t-mo and AT&T sims in.
Can't help you when it comes to AT&T as I'm in Australia these days, but we've had mixed results. My wife has a Blu Pure XL and I use a OnePlus 2. Both of us have SIMs on Virgin (Optus reseller) and Telstra - mine are prepaid, hers are postpaid.
In her case, having both SIMs activated leaves her primary Virgin SIM nearly useless. She can surf the web but no other apps work over broadband (including Email, Hangouts, Location services). If she takes it to a Virgin store and finds a sympathetic employee, he/she can go and "reset the back end" of her account and everything starts working again - for about a day or so. Other employees simply check the settings and proclaim it's a software problem with her OS.
In my case, everything works normally - except when I'm at home. When at home I need to disable the Telstra SIM (data-only) on my OP2 in order for the Virgin SIM to work in any capacity. I've checked and my local tower supports 2G, FWIW.
Of course, Australia and the U.S. are not known for dual-SIM phones - they're more popular in countries where you can't rely on having coverage from any one company as you move about. It's arguable that dual SIM phones potentially cut into the market of any individual mobile provider, so I doubt you'll find anyone willing to support them.
I doubt any provider will actively block the feature, but if some quirk of their setup causes you a problem, you're probably on your own.
For what it's worth, I've seen both the OnePlus 2 and the Blu Pure XL use dual SIMs perfectly well. Just - not all the time!
