the link on your website mentions (text copied below) .... What does one conclude from this. All we have to decide is what to do with the INFORMATION that is given to us

This is incomplete information ... Sony is not giving full details of the product.

Handle calls on both SIM cards

Dual SIM smartphones come with many advantages. They allow you to separate work from play – and handle your calls more cost-efficiently. With our new dual SIM feature, you can keep both SIM cards active at all times – meaning that you can talk on one SIM, and still receive calls on the other, instead of going to voicemail. This gives you the option of putting the first call on hold while answering the one coming in. So you need never miss a call. You activate the dual SIM feature when you set up your phone. If you add your second SIM card later, you can always access the setup guide from the Settings menu.

Yes,but there are also 2 versions of dual SIM:dual active and dual standby.Read more and you will see.T2 Ultra is dual standby,which means one SIM is disabled while the other is active:

Automatic allow both SIM cards to be on standby waiting for a call/data connection. When a call/data is established on one SIM card, the other is no longer active. Callers to the other SIM will hear a message that the phone is switched off or they'll be redirected to voicemail if any. Although, starting from 2012, the phones using chipset MediaTek MT6575, can provide the ability to receive a call on both SIM cards even when an active data connection is established on first SIM card, using only one transceiver.

Where is this Dual Standby mentioned on the website in product features. Sony is hiding details.

It is clearly mentioned, talk on one and still receive call on another. This means, it should be Dual Active and not Dual Standby.

The dual sim feature is also not working. 'Network Error ' every time i try. A lot of software bugs in this phone.

That is because the phone is dual standby,that is why you get network error.

I am referring to the option of 'Dual SIM Reachability' as shown in the attached image. This also does not capture the mobile no automatically for SIM 1 & gives the "Network Required Occured' when I put it manually.

SIM 1 is the one which is used for data.

Does the same happen if you set the second SIM on GSM only?

Re: how to make dual sim active

kamathsonline — Tue, 29 Apr 2014 09:15:58 GMT

I have uploaded the screen shots of the Network settings for both the SIM Cards. The second SIM does not have the option for selecting the Network Mode. SIM1 is used for Data & there is no data plan on SIM2

I keep moving from Home to Roaming network daily, so cannot keep the network on manual selection, have to keep it on Automatic

You should get to closest sony service for further help.

@alexdon,

There is no use in going to the neareast service centre. This is again a software issue and need to be fixed by sony developers. Every T2 Dual handset sets the same config and issue as mentioned in the above screen shots.

Ref to the earlier snapshot I had uploaded which showed the mobile of one SIM not getting captured, it was for a micro SIM, & the number which was displayed was of a normal SIM cut in size. Now when I replaced the cut SIM to a Micro one (64k supplied by the Operator), the numbers for both the SIMs are not being detected.

It is getting evident that the issue seems to be with the phone is not able to read micro SIMs. I have read that apart from the size, there is nothing different in the the SIMs, but then this is an outcome after chaging both the SIMs.

I am uploading the image showing now numbers detected. The earlier image had one number of the SIM which was cut.

New discoveries, hope Sony is listening & will solve these problems.

Phone auto restarts are getting rampant now 29 restarts in 7 days. I have selected the 'Send usage info' right from the first day, hope Sony is collecting this info & rectify soon.

You cannot have both SIMs on data at the same time.

Sorry to hear that you're having issues with your phone.

Regarding the phone restarting itself i suggest that you first try to reinstall the phones software using Update Service.
If the issue should still remain i think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Many operators do not program your phone number into the SIM-card which is required in order for the phone to detect it automatically. If the operator has not programmed your number into the SIM-card the phone will instead ask for your numbers when you enable dual SIM reachability.
To check if the number has been programmed into the SIM or not you can put it in another Android phone and go to Settings -> About phone -> Status and see if your number is displayed there automatically.

If the dual SIM reachability doesn't work or give you a network error, please contact your operator to make sure that you are able to forward calls with your SIM and subscription.

Only one SIM-card can be on the 3G-network so when SIM1 is set to WCDMA preferred or WCDMA only, SIM2 will use GSM only and you can't select network mode for it. If you were able to change SIM2 to WCDMA preferred or WCDMA only this would set SIM1 to GSM only.

t2 ultra second sim is only 2G

andyoff — Tue, 01 Jul 2014 00:38:15 GMT

Hi sony,
why the 2ndsim of xperia t2 ultra is configured only for2G? consumes lot of battery power due to 2G. It would have been more efficient had it been also made for 3G.

Re: t2 ultra second sim is only 2G

_alexdon_ — Wed, 02 Jul 2014 13:58:37 GMT

Actually 2G needs less resources than 3G.And that is how dual standby devices work.
