My sim is in my n9

The Best Smartphone Ever™! Nothing, not even the N900, can beat it on usability. The battery life was something modern phones can only dream about:I still get solid 10 days out of mine. It's 9 years old and still going strong (though I admit I replaced the battery 3 years ago.)

The only downside, it does not have WiFi and, somewhat less important, GPS. Otherwise I would never have even started looking for a replacement and found the glorious N900

I actually hated my previous E71, it used to have A LOT of problems, and each 10 mins it wasn't reading the SIM card properly But I was so happy I got rid of it.
