My first thought is that the SIM card is not inserted firmly or correctly. If it were not truly unlocked, it would give a different message such as Invalid SIM card.

If it was not inserted properly, it would read Insert SIM Card.

yeah the insert sim card went away, why wont it work with a nextel, i thought all sim cards were interchangeable? i.e boost, t-mobile, nextel, sprint....etc....

so you have nextel service witch is IDEN and your using a unlocked 8100 from a GSM service and your trying to use the nextel service ? won't work incompatible

oh....that sucks

ya sorry bro nextel is nextel as they are IDEN the only one your unlocked 8100 will work with T-mobile Cing and a few others CAD ones
