T-Mobile UK Users - Important Information re Voicemail Issue

Anyone using, or planning to use, the HTC Touch Cruise on the UK T-Mobile network will very probably need to do a special setup on their device to get voicemail access working properly.
The symptom is that your callers will be able to leave you voicemail messages but you will not be able to pick them up from your phone. When you get a voicemail message you will get the notification but when you press the soft key to access voicemail it will dial the number but you will then get an error message saying "access to this number is barred" and the system will hang up on you.
If you try accessing voicemail by holding down the "1" key or by explicitly dialing the voicemail access number retrieved from the network (probably of the form "+44050<your mobile number minus the leading zero>" or ""+44068<your mobile number minus the leading zero>") you will get the same message. Dialing 222 will work but will also initiate a voicemail setup message each time and however many times you switch your phone on and off to reload the voicemail settings from the network it still won't work.
I just spent 2 days with the very helpful T-Mobile support to sort this out, ultimately getting escalated up two levels in the technical support group, until I got someone who recognised the problem.
The issue is simple to resolve. The problem is that the format of the voicemail access number that the T-Mobile UK network pushes down to the handset is incompatible with the HTC software on the Touch Cruise (and maybe other devices too). The thing the software doesn't like is the "+" at the beginning.
To fix it go to the Settings/Personal/Phone application and click the second tab ("Services"). Now select "Voice Mail and Text Messages" and click "Get Settings...". You should now see a screen with two access numbers populated, one for voicemail and the other for text messages. Both will probably start with "+44". The text message access number is OK so don't mess with that but the voicemail access number won't work with the UK network. Simply replace the "+" with "00" and click OK and then your voicemail should work as you expect.
I haven't tried accessing voicemail outside the UK so it is possible that the above might break your access when roaming and you might need to edit back the "+" when travelling. I'd be interested in knowing if anyone has any experience with non-UK access and a "0044..." setting rather than the default "+44...", does it dial the UK access number OK?
(Actually, I never looked at the mechanics of accessing voicemail outside the UK, does it still dial the UK number or does the host network automatically push an alternate local access number to your phone when you register with the network?)

Nice on Julian. I bought an Orbit 2 on O2, but my number doesn't transfer to O2 for few days yet, so have been using my T-Mobile SIM, and also experiencing this problem.
Thanks for sharing the tip!

I'm on UK T-Mob Web&Walk. Switched the +44 entry to 0044...but my TC then coundn't send texts. Switched it back and fortunately can still access voicemail as well as send texts. Strange.

I'm with T-mobile running an old T-mobile sim card on my new TC, when first called voice mail it gave me a long introduction then said "turn of your mobile off and on again to not get this messages again", I turned TC to "air plain mode" back to on mode and everything was cool from there on.
It seems that not everyone have that problem OR T-mobile has sort out that problem after Julian told them about the problem. In any case, thanks Julian to share this with us.
PS (today after reading this post is the first time that I use voice mail with my new TC)

Similar problem on WM 6.5 Asus Crystal
I had exactly this problem with T-Mobile and WM 6.5.
T-Mobile technical support was excellent, ringing back on several occasions to ensure that the problem was fixed, even though my handset is not a supported model. Once I was put through to 2nd layer support they fixed it in seconds.
In a nutshell, if you text and voice service centre numbers begin with a +44......, change them to 0044......
This did not happen on my XDA Exec WM5.0, so appears to be a new thing in WM6.5?

100 carrier msgs in 1 day!!!

UPDATED
I´ve just been using the HTC ONE X for about 4 days and I´ve been receiving hundreds of repeated msgs from my carrier. They say "Vivo RJ 21" (Vivo is the carrier, RJ stands for Rio de Janeiro...the city, and 21 is the area code for Rio de Janeiro). I´ve already tried several factory resets with no luck. I´ve also tried a micro sim card from a different carrier and I kept receiving the same msg (except for the carrier name). I´ve received other regular msgs from my carrier and from other people that were not repeated. It´s just this one.
What are my options here????

Do you still have the same number ported over? If so then maybe it might be a glitch in there system. If not then it might be spam from the poor person before you. Either way either get a block on that or call carrier to stop it.

The worst part is that I cannot even block this number because whenever I try to add the number to the Mr.Number app it tells me to add a valid number. The number is only 2 digits...it´s 50

Looks like it would be best to either call them or go in store and ask them to test the phone. Sounds more like a software hiccup, but who know? Hope you don't have to receive that many texts tomorrow

But do you guys think there is a chance this could be phone related?
I might just try to get a micro-sim to sim card adapter and test it another phone to see if it still happens.

Its a broadcast message
U can stop it in message setting
It will not harm u
Press thanks
Or u can give me ur one x as a gift

How do I stop that in settings? I´ve tried everything and I don´t think it´s that simple.
It must be getting close to 200 messages.

Just go to your carrier already! Or if nothing works, then do a barrel roll~

Don´t you think I would have gone to the carrier if it wasn´t closed during the weekends! I´ve already called them 3 times and they did different things. The last thing they did I was supposed to wait 24h.
What is a barrel roll?

Can you remove the SIM and use the phone without it? If not then try finding some other app that blocks numbers... maybe one that supports blocking operator numbers?

as said before carrier messages can be blocked...I'm assuming a battery pull did nothing?

Ok, just let me know how. So far I´ve tried about 7 differente text/spam blockers apps and none has worked.
The HTC One X´s batt cannot be removed.

Do you have message settings
Just check there might be option of broadcast message
Keep our forum clean

I do have message settings but there are no options there that would help me with this (only stuff like notification types, signature, forward to email, etc).
Today I´m going to the store where I got the micro sim card to have it changed. I REALLY hope it works because it would be a real shame if this was the HTC One X and not the micro sim card.

When I go to "about the phone", then "network" it shows:
operator name - unkown
signal strenght - 0
mobile network type - unkown
service state - radio off
roaming - not roaming
Nonetheless I can make and receive calls, send and receive text msgs, navigate, etc. The only issue is really the operator msgs informing my city area code over and over again.
I went to the carrier and got a new micro sim and did a factory reset WITH the micro sim card inside the phone. The date above got populated. I will wait to see if I will get anymore msgs but I think this might be it.

I´ve tried with a micro sim card from a different carrier and the problem persists. This is phone related for sure. I really don´t know what else to do...maybe try a different rom other then the stock?

I´ve called HTC again and they instructed me to do the following:
-> "settings", "call" and then disable the option "cell broadcast".
So far no msgs. Lets wait and see.

Sms scheduler and network Carrier

I have been to many posts on android sms apps but haven't found anything good.
Features Necessary:
1. Scheduler
2. Should tell what carrier the message is from
I tried using chompsms but it doesn't show what sim the message came two for my dual sim phone. Like stock app shows carrier/network label along with date
Which becomes a problem on dual sim phone where you don't know about what sim has the offer talk time or from what sim you should reply back to save money, because sms are free or cheap on same network Carrier compared to sending from other.
So please suggest app which does both above mentioned things.

Review Of 'Dual Sim Control' – Dual SIM Management App for Mediatek Based Phones

NOTE: This review was written when the app used to be called 'MTK Control'. So any references in the text to 'MTK Control' now refer to the app's new name of 'Dual Sim Control'.
I have been using chinese dual SIM phones for quite some years now and love the facilities they provide. I can have both my work SIM and my personal SIM in one device rather than having to carry two phones around with me as I used to. Also using the dual SIM solution allows both SIM's to be connected to the hands free system in my car so that I can make and receive calls on either SIM through the car system.
However, there has always been a downside and that is the SIM management facilities built in to Android. When making a call or text, when you press the send button a box will pop up asking which SIM you want to use to make the call/text which you have to select before the call is made. There is a facility whereby you can assign each contact in your address book to a particular SIM but even this does not automatically make the call using the assigned SIM. All that happens is that when you make a call/text the same box will pop up asking which SIM to use and the only difference is that now there will be an indicator next to one of the SIM's recommending it based on the SIM assignment but you still have to manually select it. Now I don't find this a particular problem when using the phone normally but it is a major problem when using the phone via the hands free system in my car because when I make a call through the car system the box still pops up on the phone asking which SIM to use which is a big drawback and means that the phone has to be accessible and visible while in the car.
However, I have now found a great solution that I have been using for about a month now and is working great. It is an APP called 'MTK Control' which is available through the Google Play Store and is available as a free version and a premium version. I would suggest testing it with the free version first to make sure it will work with your phone but if it does work ok then I would wholeheartedly recommend purchasing the premium version which is only 79p (around $1) and adds additional functionality like homescreen widgets etc.
So, what does 'MTK Control' do that the built in SIM management does not. Well, everything to be honest. Firstly it gives you toggle actions to turn each SIM on/off or to toggle calls between the two SIM's and also to toggle the data connection between the two SIM's.
All of these functions can be added as widgets to the homescreens in the premium version as shown below.
However the best part comes with the ability to create rules to assign contacts and numbers to a particular SIM and have that SIM used automatically with no user intervention required. This is done in the following screen.....
….where you can input a single number, a group of numbers using wildcards, an individual contact or a group of contacts and then select which SIM you want to assign this rule to. So the following screen shows that the contact groups 'Family', 'Friends' and 'Services/Shops Personal' are asigned to SIM 1 (personal SIM) and the groups 'Coworkers', 'Customers' and 'Services/Shops Work' are asigned to SIM 2 (work SIM).
There is also an auto learn function that can be activated so that the first time you dial a new number or contact it will ask you which SIM to use but it will then automatically create a rule for this number so that in the future it will be automatically chosen.
The best part about this is that it works seamlessly with the hands free system in the car. When I initiate a call from the car system the phone will automatically select the SIM to use based on the rules that have been setup. This means that I don't need to physically access the phone at all and it can stay in my pocket.
In my view this app does what the built in SIM management should have done from the start. The developer of the app is constantly updating it with new features and is very approachable and takes on board feature requests.
One word of note, as the title of this thread suggests, the app will only work with Mediatek based mobile phones and will not work with phones like the Samsung Duos range etc. I personally have tested it with the following phones:
UMI X1S (MTK6589)
Jiayu G3 (MTK6577)
Jiayu G4 (MTK6589)
Jiayu G4S (MTK6592)
I haven't used the text or data functionality so can't comment on that specifically but the call related functions and the calling rules I use all the time and have worked flawlessly.
NOTE: This app is now called 'Dual Sim Control' and is now compatible with Samsung Duos phones as well as MTK based phones.
I have no connection whatsoever with the developer of this app. I am just a very happy user of it.

Update: Edited top post to reflect this additional information.
I have now tested and can confirm that 'MTK Control' also works on the Jiayu G4S phone which uses the MTK6592 Octa-core SOC.

Hi,
Thanks Russell for the review.
I'm the developer of this app, and if you have any doubts regarding the app, suggestions, or problems with any function please contact me directly using the contacts available at the Google Play app page or (as long as Russell doesn't mind having his thread slightly hijacked) ask here.
Thanks

Hi Russell,
I have a G4s but don't seem able to get it to work right, can you confirm that you are using the kitkat rom with this?
I have bound numbers with the app and with the system but still asks me for a sim when dialling via Bluetooth.
Any help greatly appreciated!
Thanks

Hi,
Can you post the configuration you have on MTK Control, and on Android Settings.
Do you have any contact SIM preference defined?

Thanks for sharing.

Hi,
what info do you need?
I have some numbers as preferred in contacts (they show a little symbol and the sim card name next to them in the phone book) and added some rules also in mtk control, and slid the enable button on and it said always validate, but still get the box pop up saying which sim.
Let me know if you need anything else, and thanks for looking at it.

Hi,
try to remove all the preferred contacts in Android settings, and then set on of the SIMs as the preferred one. This way I think that the Android popup to select SIM should not be shown.
Then you use MTK Control entirely to select the SIM used to dial.
Please tell me if this helped.

is confirmed working on kitkat ?, I have huawei honor 3c. thank you
I confirmed that it works off sims, but not to create rules, always asked to choose sim, its free version. my phone huawei honor 3c

Hi,
I've made an upgrade last week to improve KitKat compatibility.
However, the best is to try the free version like you did. There is also a grace period on the payed version (not in-app purchase, only on the full version) so you can always try all the functions and cancel the order to get refunded.
Regarding your problem when you say that you are always asked to choose sim, you're talking about a MTK Control popup or the stock Android popup? If it's the latest, look my previous post where I explain how to get the best experience with the Call Rules.
Regards

Hi
Sorry for delay, did a full reset of phone to make sure no other apps messing with it.
No sim associations are set in android.
voice calls set to always use one sim
Rules created in MTK control to use second sim.
Phone will dial via Bluetooth speech recognition and appears to choose the sim but call ends without ever connecting. No box pops up asking for sim choice, interestlingly if the screen lock is off the calling screen doesn't show either.
I can hand dial a number and it appears to choose the sim and show calling screen but uses Bluetooth for voice.
Any other ideas?
Thanks

So if you dial using Bluetooth the call is never made... but if you dial from phone with the Bluetooth connected it works as expected?
Can you send me the application debug information after replicating the first situation?
Thanks

Hi,
can you please try to increase the time before the call is made using MTK Control settings?
Try it with 0 ms delay or with a delay like 500 ms.
Tell me how it goes...

Changed the delay to 500ms and this has fixed it, now dials via Bluetooth speech recognition and call connects.
Many thanks for the advice and help.
Steps for anyone else having an issue.
1.remove associations in android
2.set sim association in MTK control
3. set a sim as default for voice in android
4. set time delay to 500ms in MTK
Thanks again

as remove associations in android?. thx

Hi,
In Android settings you can define one of the SIMs as the prefered one for a given contact.
This associations induce, in my opinion, a not very user friendly behaviour even .when not using my app.
You should remove them to make sure that my app can work it's magic without interferences.

Hi,
I believe that it doesn't work, but you can try it with the free version. I'm however preparing a new MTK Control version that will bring support to Android One and Samsung phones.
Join the Google+ community since I will announce there when it's released.
Thanks

This APP looks great but you clearly state it will not work on other phones, like my LG G3 so I was wondering if you know of any other APP like this that will work on a normal LG G3 dual SIM phone ?
Thanks mate

Dual sim Whatsapp/internet share?

Hey, there's a remote location that I'm going to every now and then, and there's good signal only by a specific provider.
There's no good signal with that provider where I live, so switching permanently is not a solution for me.
I've purchased a second sim for when I'm going to that location, didn't try it yet but I wonder about using my Whatsapp with that sim.
According to the Whatsapp FAQ:
"Your WhatsApp account can only be verified with one number on one phone. If you have a dual SIM phone, please note that you still must choose one number to verify with WhatsApp. There is no option to have a WhatsApp account with two phone numbers.
If you attempt to frequently switch your WhatsApp account between different devices, at a certain point, you may be blocked from re-verifying your account. Please don't repeatedly switch between different devices and numbers."
About using one WhatsApp account on multiple phones, or with multiple phone numbers | WhatsApp Help Center
faq.whatsapp.com
Which means that changing the Whatsapp number every time sounds like a pretty bad solution, and I know people that had issues with this.
So basically I'm trying to ask for a possible solution here, I guess I need to:
1. Either be able to use the other number's Whatsapp with the other sim.
2. Either be able to 'forward' the internet from the second sim to the first sim.
I don't know if any of them are possible, but hopefully I'm not the first one to encounter that.
Thanks!

It would be ridiculous for verification to happen very often over SIM data connection. After all, people often travel using Wi-Fi, and WhatsApp still works, because the application only checks whether the SIM inserted into the phone is the one that was used when registering. Just turn on the internet via the second SIM, and do not turn off the first one despite the lack of coverage. At most, the battery will run out faster due to attempts to establish a connection from the first SIM to the mast.
