Weak signal everywhere

[BoredSomeone]

I've had my phone (Xperia mini pro SK17A) for a few months now, and I'm getting a bit fed up with it. Provider is T-mobile, and I would blame them, but my old phone had a better signal + I have almost NO signal while inside, for hours at a time.

My old phone was a rather old motorola flip phone, got it when it was old about 5 years ago. Since the SK17A came out just recently, I would expect it to have a stronger signal all around. But I can't call, or if I do somehow get a signal to call, It'll disconnect within a minute. I also don't get texts until have an hour later, unless I'm constantly trying to reconnect to T-mobile.

Usually when I try to connect, it will give me the message "Sim card does not allow connection to this network", which is quite wrong. It also has a signal to AT&T about 100% of the time, would be nice to have a way to turn off connection to it, so that it stops switching networks (which causes me to not get any messages until I manually reconnect it to T-mobile).

I'm honestly hoping that this is just faulty hardware, or something along those lines, because this is just ridiculous. Should I see if I can get a new one or am I stuck with this?

Check if you get the same problem setting the phone to only use the GSM or 3G (WCDMA) network.

Menu > Settings > Wireless & networks > Mobile networks > Network mode > Try with using WCDMA only or GSM only.

See if you notice any difference.

It's also a good idea to try using another SIM card if your current one is older than 2 years.

Unfortunately there is not much we can do for you here. This is either a hardware problem with the phone, or a tower outage in your area, both of which your carrier has to help you with.

It sounds like it roaming with AT&T as the stronger signal or some kind of settings mix up. I would take it to a T Mobile retailer and see what's going on (at least you'll know they have a good T Mobile signal there).
