michaelt:yuxek: i wonder why they don't just text message all their cdma customers 1 month in advance before the network closes instead of putting ads in newspapers? or can't they tell which numbers are on xt and which on cdma?
millions are probably still on cdma because XT went live only last year.
As already mentioned, Telecom have made an effort to move their customers over to XT. On Account customers will get free/subsidised phones, and for the Prepaid market they're ending (or maybe already have) CDMA $10 txt, while introducing unlimited $12 txt on XT. Most of the customers they'll have left by June 2012 will be very light cellphone users, I'd imagine a large number of them only turn on their cellphones every few months or don't know how to read a text message.
$10 TXT has not ended, it was recently extended indefinately.
