After switching Sim cards I need to re boot

Hi all,
After I switch Sim cards over from my Hong Kong Sim to my Australian Sim ( *not the other way around* ) the phone will not connect the calls. It says "Calling" but nothing happens. Then I reset the unit and it then connects the calls ok....

Anyone else have this issue?

i-phone 4, iOS 4

You should never switch SIMs with your device turned on. The proper procedure is to turn it off, switch SIMs and then turn it on.

This is true for ANY mobile phone, not just the iPhone.

Ok, I'll try it next time.

But it works ok if I switch from the Australian Sim to the Hong Kong one.

If you absolutely have to do it without turning off the device first (?) then turn Airplane mode on, switch SIMs and then turn off Airplane mode.

Well as I am in an Aircraft at 38,000' over the middle of Australia when I switch the Sim cards over I already have it in "airplane mode" But good suggestion anyhow!!

Next trip I'll "slide to power off" and see if that stops the problem.

Tks.
