Cellular Phone Forum / Providers / Nextel / September 2005nextel and southern linc
why cant you use a phone from Nextel on southern linc ? im talking if they both carry the same models . what is different that makes them not work ? With TDMA, there is data for each phone that must be in the carrier's system. This information is sent from Motorola to Nextel or SL. Without that info in their system, the phone won't work. > why cant you use a phone from Nextel on southern linc ? > im talking if they both carry the same models . what is different that makes > them not work ? >With TDMA, there is data for each phone that must be in the carrier's >system.

True, but this isn't TDMA, it's iDEN. iDEN uses SIM-cards in the more modern phones, and as long as you get the carrier lock removed, you can use phones from different providers by swapping SIM cards.  SignatureThe preceding post may have contained unsuitable materials and should not have been read by small children. iDen is the name. It is a TDMA network. > >With TDMA, there is data for each phone that must be in the carrier's > >system. This information is sent from Motorola to Nextel or SL.

However, TDMA only covers the way the available bandwidth is used, it does not restrict how the carrier identifies phones or subscribers. GSM is TDMA too, yet you don't need to register your phone with the carrier, only the SIM. You can drop a GSM SIM into any unlocked GSM phone and access any GSM network (assuming frequency compatibility) iDEN is no different then GSM in this respect, the carrier doesn't need to know anything about the phone, not even the IMEI, all that need is the SIM card number. Note that the above assumes a SIM capable phone, iDEN has SIM and non-SIM phones, if your phone doesn't accept a SIM card at all then none of the above applies. SignatureI've given up on sigs. I just couldn't think of anything clever to say. >>With TDMA, there is data for each phone that must be in the carrier's >>system. This information is sent from Motorola to Nextel or SL.

Having a SIM card does not always guarantee portability of the handset. For one thing, each iDEN carrier programs their handsets with a band map. This is the equivalent of a preferred roaming list (PRL) in CDMA, and while I'm not sure what it's called in the GSM universe (ENS?), I know there's something similar there. At any rate, bringing a handset with the wrong bandmap can delay or event prevent the handset's acquiring the "new" home network. And so far, none of the iDEN carriers seem willing to flash other carriers' handsets to work on their networks. SignatureE-mail fudged to thwart spammers. Transpose the c's and a's in my e-mail address to reply. > why cant you use a phone from Nextel on southern linc ? > im talking if they both carry the same models . what is different that makes > them not work ? Southern Linc refuses to allow Nextel roaming. earl Wrote: > why cant you use a phone from Nextel on southern linc ? > im talking if they both carry the same models . what is different tha > makes > them not work ? you can use a nextel phone on southernLINC and vice versa. You jus gotta unlock the phone with either raptor, RSS Super Depot, or if it' ROM 13 or ROM D, as of right now u will have to pay Moose to unlock it After it's unlocked, you write the csd in carrier and viola! you ar talking on another iDEN network. This applies to telus and boost also Hope this helps. That knowledge took me alot longer to find tha explain. Actually is very simple. Anything is possible. "Seek and Y Shall Find"...eventually!!! lol... : +------------------------------------------------------------------- |Filename: dnfnoob.gif |Download: http://cellphoneforums.net/attachment.php?postid=33081 +------------------------------------------------------------------- |
