Even more exhausted…

I just did a count of the SIM cards on my desk. There are 14. Wellm there are 14 activated SIM cards out in the open. There are another six in a box on the floor, and one in my phone. And another two phones without SIM cards on my desk. Can you spell GSM 🙂

In many ways I love GSM. With CDMA phones, being based on the AMPS system, you have to ring a carier if you want to change phones. And your phone number is locked to the phone too, and you must enter this manually into the phone (although some phones these days can be auto-configured). With GSM, everything is stored in a database back at the server. The SIM card just contains a serial number and an encryption key so that it is hard for people to listen in on your call over the air. Not impossible, but hard.

Testing equipment is easier with GSM since you just swap a SIM card. When the SIM card is set up correctly…

With all this on my desk, I think I need a holiday…
