Help with Hero losing signal

---

Hello everyone.

Recently, my hero has been randomly loosing signal to my network provider. It seems that if I use the phone, it never looses any signal, but when I unlock the phone after a while, I see that it has no service. If from there I put the phone in airplane mode for a few seconds, and then turn airplane mode off, it generally catches the signal again. Also, if I scan for networks manually, I can see all the networks in my area, but I receive a message saying that my SIM card does not allow this connection.

Also, this has happened throughout a number of ROM's and Radio's, so it cannot be ROM specific.

Has anybody else got any tips or ideas as to why my signal is dropping? I can also post my logcat later today if it will help.

Thanks!

I have this problem .
I can not call or receive call.
Help us please ...

it can be your radio that might be causing the problem?

try updating your PRL

Thanks for the support guys. It turns out that my SIM card was actually kicking the bucket, and so I went into Virgin Mobile, and they replaced it in 5 minutes. So far, no problems...so it seems sorted.

Thanks anyway!
