Hi,

I bought what I believed was an unlocked phone from carphone
warehouse. A vodafone sim works in it and an o2 sim works in it but
not a t-mobile sim.

I tried another phone which came from asda. Same story: the t-mobile
sim will not work in it but other sims do.

When the t-mobile sim is used, the phone powers up but the "t-mobile"
does not appear in the screen as if there is no network. There is also
a funny symbol: it's an arrow a bit like a mirror reflection of an L,
pointing across and up but t-mobile don't know what it means. It
appears on both phones.

What does it mean? Can these phones be unlocked to both o2 and
vodafone but somehow locked to prevent t-mobile sims?

The t-mobile sim works in an old t-mobile phone I have and has been
tested in several phones in the t-mobile store and it worked in them,
so I think it is unlikely to be a faulty sim.

They don't know nor do I! Do you?

Thanks.
Stephen.

At first glance I'd have said it was working OK on 900 MHz but not 1800 MHz
but the Asda SIM ought to have worked (AFAIK it uses the Vodafone network),
but it looks like some sort of block on what networks can be used.

With no info about what phone (make and model) it's a needle in a haystack.

You don't say what the phone is.
Is it dual band?
O2 and voda use one band whereas T.Mob and Orange use another

The asda sim does work, it's t-mobile that doesn't. It's a nokia 2330
classic, so a basic phone but even so it is dual band (just checked on
the nokia site), I wouldn't have thought anyone made single band
phones any more?

Actually Voda and O2 use both bands - T-Mob and Lemon do not.

Try an Orange Sim in it, if that doesn't work the phone is faulty on 1800MHz

The last monobanders were Nokia 51xx of 1997

Is it possible that the phone's imei is in the t-mobile blacklist? A new
phone imei shouldn't be blacklisted, but that doesn't mean it's impossible.

As other posters have suggested, try an orange sim - if orange and
t-mobile both fail I'd guess it was an 1800 fault.

You say it's dual band .... could it be dual band 900 / 1900 (usa
standard) and not 900 / 1800?

I don't know. I'll have to contact T-mobile with the imei and see. I
know it is written on the box but is there a # code you can type into
the phone to get the imei?

Don't networks share blacklists, so that a stolen phone on t-mobile
would be blocked by all other networks?

t-mobile both fail I'd guess it was an 1800 fault.

I don't know anyone with an orange sim. Do they give away freebies?

I bought it from high street branch of car phone warehouse so I would
like to think it is a UK model and brand new, not stolen but something
has gone wrong somewhere!
