I called T-Mobile today to discuss Multi-Sim.
It’s actually quite complex.
Here’s the concept: You have, let’s say, three phone numbers on your T-Mobile account.
You nominate one of the phone numbers to be a master.
If you make a call from any device, the master number is used. So that I could call you from my N93, or my E61, and you’d still see ‘Ewan calling’ on your phone. Neat.
Likewise, if you call me, I *gather* (though I didn’t specifically confirm this) that all phones will ring. I didn’t confirm this because I was too busy trying to understand how things worked if I sent a text message from one of my handsets.
So. Let’s be clear:
E61 – Master
N93 – Slave
K800 – Slave
N73 – Slave
So each of these phones has to have its own price plan. That’s a total arse. They have to each have a separate number on your account.
Then you apply the ‘Multi Sim’ option which means that any calls you make — e.g. from the N73, will appear to come from your master number.
Send a text message from the N73, and that uses the N73’s own number as the originator. Arse.
THEN you need to convert your account to a business account. That’s an arse in itself.
In summary, Multi Sim is not what I wanted.
I wanted four or five sim cards, each tied to ONE account. So when I call, text, or whatever, from whatever device, you know it’s from me. And that when you REPLY I get the text message on every device. Or something.
Yeah, it’s an arse. Total arse.
Someone’s going to have to fix this properly, at some point.
So Multi Sim from T-Mobile is a cool service for a particular subset of persons. Not me, alas.
