So I have a cellphone that does GSM 900 / 1800 / 1900 / UMTS 2100 that is currently on Vodafone. Will Telecom's network ever be able to support this? If so how? New SIM card?
Thanks in advance

eXDee: So does this mean any basic vodafone phone wont easily be able to be switched to telecom? UMTS will be cities only?
I assume a software update cant alter the radio in it?

inquisitor: I wonder if Telecom will also use UMTS850 for their new network. UMTS850 has about the same range as GSM850, but is way more efficient in terms of capacity and it brings a lot of advantages, such like way better indoor coverage than UMTS2100 and broadband data service. On the other hand UMTS850-handsets are rare, so most roaming customers can't get on a UMTS850 network and that means less roaming-income. But actually GSM850-handsets are also not the widely spread and further with Telecom's wide spectrum they could use GSM850 and UMTS850 simultaneously, after a Spanish field test by Huawei, Qualcomm and Telefonica confirmed interoperability of GSM and UMTS in the same spectrum. That again would be more expensive during roll-out, as dualmode infrastructure would be needed, but a GSM850/UMTS2100-strategy would however be antiquated.
sbiddle: Telecom's plans are only for GSM850. They simply don't have the bandwidth to run both CDMA + GSM + UMTS in the 800MHz spectrum that they own.
Have Telecom already published the name of the network equipment supplier?

Never say never... it's amazing what you can fit into 15 MHz, with the right motivation ;-)

inquisitor: According to this article Alcatel-Lucent have also successfully tested the coexistence of GSM and UMTS in the same frequency band (900 MHz). I wonder how much spectrum you need for the dual usage of the same band, especially if guard bands are needed and if so how wide they need to be.
inquisitor: So VF's UMTS900 network is a huge threat to Telecom, that forces them to deploy UMTS850 very soon.
