T-Mobile Multi-SIM SMS Focus Toggeling

Daniel Nashed  26 September 2009 17:31:33

Now that I have switched completely to T-Mobile I have 3 SIM cards -- all with the same mobile phone number in the same contract with the same invoice and conditions.
You can get up to two additional Multi-SIM cards for 30 Euro each which allow to use up to three devices at the same time.
You can surf in the internet, receive a call and have one additional outgoing call all at the same time.
The only limits is SMS. You can only send and receive short messages on one SIM card.

But you can switch the focus for sending and receiving SMS to another device.
You only have to dial the GSM code *222# wich will switch the focus for sending and receiving SMS to the current SIM card and device.

This GMS code is quite undocumented (even customers asked for it at the hotline did not get this information) but very helpful in case you are a T-Mobile Multi-SIM card user.

I have switched from Vodafone to T-Mobil and I have the preception, that T-Mobil has a much worse network density and reliability. Even though it is like Vodafone GSM 900 in-room reception is much worse compared to Vodafone. I am even loosing connection driving the autobahn. That has not happened to me for many years. What are your experiences with T-Mobil? I know it always wins the connect magazin award, but can the voters really compare?

The voice service on Vodafone also worked a bit better than at T-Mobile. But I am still much happier with the over all service of T-Mobile.

The combination of all services works very well for me. Even voice mail is not as good as at Vodafon.

It might also depend on the device in some cases.

Having 3 SIM Cards in 3 phones doing 3 things at the same times sounds quite uncomfortable. For sure while sitting at the airport and trying to kill the waiting time.

On a BlackBerry Device you can do all 3 things at the same time on one device with 1 SIM Card. It has multitasking capabilities and you can even copy from the Internet the info to the SMS and make a comment during phone call and attach that info to the call log. All that by simply jumping between these tasks while they are all open. Also Conf calls can be made or separate calls at the same time.

Give it a try. For sure easier than handling 3 devices at the same time.

hmmm... that wasn't the point of my posting. sure I can do multiple things with the same device -- not all works at the same time with the iPhone in every situation yet.

The main point of my posting was how to switch SMS to a different multi-SIM card.

I have one card for my UMTS stick, one for my iPhone and one for additional test devices. they are all part of the same contract without no extra monthly costs.

Blackberry is rock solid business device and the only really enterprise ready solution but the iPhone with Traveler is very cool with very good integration between email, contacts and all sorts of other applications. and there are a ton of great applications which are not just for fun applications.

I will never give my iPhone away ;-)
