Hi people,
I've searched the forum for an answer to my question, no joy so here goes on a new thread.
I recently bought myself a Chinese dual sim smart phone, named "Longhorn" (no sniggering!), but pretty sure it's better known as a STAR MTK6573. Great phone for the money, 1GB processor, all the bells and whistles. My problem is that I want to use two sim cards, one from a British network, one from a Norwegian network. Right now I'm in Norway and the Norwegian sim is working faultlessly, the British sim works when the phone is switched on first, but then after varying amounts of time the British sim drops out of service. If I turn the phone off, then restart the UK sim comes back into service but again goes off after some time, sometimes minutes, sometimes hours.
I've looked through the sim related settings but can't find a solution, and even contacted the British network operator to see if they know any answers - they don't.
I'll be going to the UK shortly so it'll be interesting to see if the Norwegian sim starts cutting service when I'm there, in the time being does anyone have any ideas for a permanent solution?
Thanks to all for reading, and musing on the problem, in anticipation.

Did you try switching the SIM-Slots ?
Are both using same freq ?
Did you used Sim-Turbo or other "perfect unlockers" ? <- im asking because after using one of those "great" inventions my SIM started to droping signal on diffrent phone (like the X-Turbo/X-Sim/Sim-Turbo) install some junk on sim...

Hi, thanks for your answer. I haven't installed any sim "enhancing" software, and the phone is brand new. Swapping the sim slots doesn't seem to make a difference, even though only one is WDMA. I think the problem is to do with roaming from my UK sim, when the signal strength drops out the sim loses service to the roaming network, but doesn't reinstate the service when signal improves.
Update
OK, so a little progress was made! The phone only has the option to set one of the SIMs as 3g. The local SIM was set as the default and therefore had the 3g setting applied to it. If I force change the 3g to the roaming SIM the roaming SIM stays in service for longer, and is more stable but still loses service periodically (at least twice a day). Any further suggestions?

OK, so I now have a working dual sim phone using two networks from two different countries. My initial headaches were all caused by the overseas network SIM. Either faulty or incompatable but after a SIM swap from the network company it now works faultlessly.

Hi, I have a unlocked Wizard & my T-Mobile contract has just expired, I was just wondering if a 3G sim (3) would work in it as there are some cheap deals on that network? I wouldn't use it for video calls so thats not a problem.
im 99% sure they DONT! however maybe someone there can prove me wrong
I'm using a Cingular 3G SIM in my 8125 with no problems at all.

what our american brothers call a "3g" sim and what the network provider called "3" use are slightly different things.... a american 3g sim is simply a normal 128k provisioned with extra services I.e. data and video calling (this is the same way all the gsm uk networks work too) however with "3" being the first 3g only network in the world they choosed to use the next generation of sim card called a usim which don't work in lots of non 3g phones including the wizard. try googling the word "usim" to see wot I mean
Under 3's terms and conditions you are not allowed to use their sim in a 2.5g phone. If you do use one and it works, they will eventually block it and send you a new sim with a gentle reminder that you are in breach of Ts and Cs.
Cheers Chaps, 3 it isn't then!
My O2 UK 3G UMTS sim works perfectly in my Wizard.You just can`t really get the benefits from it (Faster GPRS/EDGE etc....).
Since some months I'm in Egypt for business reasons. I don't use my hermes very often here, because I'm having some duty phones. More or less I'm playing around with it, every now and then I'm turning the radio on to look for text messages from good old Austria.
I'm using an Austrian ONE Sim card and roam with Vodafone Egypt. In the place where I'm leaving I have 100% net.
Some days ago - I was testing S2U2 - I noticed that I can not call my hermes while the Austrian Sim card is inserted. I tried it with two different duty phones with Egyptian Sim cards, I tried it with another phone with an Austrian Sim card in it, its always the same: "The number you've dialed is incomplete". Of course the number is not incomplete. I can make phone calls from my hermes with the Austrian Sim card in it, but I can not call it. BTW: I tried it with UMTS on and off, same result. Its working fine if I insert an Egyptian Sim card, so apparently its a roaming problem.
Its not that important, because I don't use roaming with my hermes (too expensive, thank you very much ONE *ggg*), but I'm curious whats going on. Guess its a problem caused by my home provider?
Any ideas?
Hi there.
I have a friend who has an X1. He is reporting that the X1 is working with his O2 sim card and working on Vodafone however it isnt working with his Latvian sim card (in the UK) (i.e. Tele2 and LMT). Are there any settings you need to change in order to enable roaming? Is it possible for a phone to be country-locked?
Thanks,
Lawrence
It might be the phone is locked..then again it might not be.
What does he see when he puts in the card? How long do you wait while it searches for a signal? (Sometimes when I'm roaming it takes a few moments -in egypt I think I waited 2 minutes - it might take longer for Latvia to register for one or other reason).
thanks for your quick reply!
I dont think it is locked because it works on both O2 and Vodafone fine. I bought the phone from vodafone and all of their phones come unlocked.
its more likely that the phone isnt using the correct setting for the service provider... usually when the phone detect a new sim it will ask you if you want to change your settings... your friend may have missed it and didnt change the setting so it didnt work
Roaming is enabled by the origin network, not by the phone.
There is a chance that some of the UK networks don't allow those SIMs to roam on their network, but you would need all 4 for them not to work.
another reason could be too old incompatible sim card
people have from time to time reported rather old sim cards being
incompatible and solved it by getting newer sim card from their operator
Hallo,
I have a world-wide gsm version of the htc Hermes. The device is simlock-free and always has been. I put the official, albeit leaked, WM6 rom on it and it works great. But: last week I switched providers (for better data plans) and here is the result:
Data connection works just fine
SMS works just fine
But, I can hardly make calls and I don't receive any. The problem is not the network, because I switched phones (I put my SIM in a €26 SamSung phone which I use when I go camping) and I receive all of the calls. When someone calls me, they hear silence for about 30 seconds and then end up with my voicemail.
Any ideas as how to solve this? Both my old and new carrier are GSM. The only difference between them is that my old carrier (Belgium, Proximus) uses has a 3G/HSPDA network whereas my new carrier (Belgium, MObile Vikings; uses the network of BASE) has an EDGE network. Both operate on Dual Band.
EDIT: Would a radio upgrade do any good? If so, any suggestion for a radio version?
Thank you!
Come on, 80 views and no reply. Someone must have had an idea!
I did a radio upgrade (1.48-> 1.50) but that didn't solve the problem. Any other ideas?
I have TyTN and similar problem. Installed WM6, and worked fine for a 6 months. Few days ago problem (Strange?) started. I have GSM signal, I can make calls, I can receive calls from fixed lines and other GSM operators, but I can't receive calls from users of my domestic network?!? They get info Connection error? Please, HELP.
Also, when I ask request service for Call Barring I get info "Can't read specified service..."
Change the Sim
Long shot but have either of you thought to get a new sim from your current provider (port your number across if necessary) and see if that works?

I've changed SIM card, it's still same problem! But, with a SIM card of other mobile operators I have no problem.

Sounds like a problem that's related to the network provider you are using. Have you chased down their technical dept for help? All else fails, move providers.
Once had a problem where I could not get mobile signals at home but could everywhere else. Turned out my service provider had issues with broadcasts to the cell near me.
They fixed it and gave me my charges back equal to the time the system had been out.
Good luck with it.

HI EVERYONE,
Hope you can help me or give an advice...
I got Xperia Z5 Dual Sim Card phone. I'm on UK network. If I use both sim slots with the same provider, one of the slots stops working immediately. Shows no signal bars whatsoever. As soon as I use two different sim cards from different providers, both work fine. I called my network provider, but they state it's a phones fault.
Has anyone experienced anything like that?
Can you buy new sim card? And try with the new one

Could it be your carrier doesn't have GSM coverage in your area?
I think 3 in the UK does not have GSM. When you are in 'dual standby' mode one of the SIM cards MUST be on GSM only mode, therefore if your carrier doesn't have GSM it will never connect. This is a funny limitation, but it's what allows for dual standby phones to be made relatively simple without having to have two radios for two carriers, which would make the phone a lot bigger and complicated.
I went to the actual store and swapped the sim cards, but nothing helped

I never thought of that... It's strange as I went to Vodafone store and they said they don't support dual sim card phones at all.
I am actually with network 3, so thought there shouldn't be issues like this. Another funny thing is, that if I swap the slots with the same network 3 sim cards, sometimes slot No1 and sometimes slot No2 isn't working. As soon as I put one Vodafone and the other network 3 sim cards, both slots work just fine

I used my Z5 Dual when I was in the UK and was having real problems getting the EE sim card to work on the data side, it seems that when I put in the EE card my phone restarts (annoying but standard) and it resets the data preference to 3G which meant that I had no coverage. As soon as I switched the data preference to LTE it was up and running full guns again.

Thanks for you answer. Seems that it's more to do with the provider then the actual phone.
Sad that phone like this couldn't be used to it's full potential
