Well it had to come one day , my CAT CDMA Novatel MC727 USB modem that ive had for many years , has started to play up , the annoying thing is the modem seems to have an intermittent fault , if it had just completely stopped working then ok thats it . The modem seems to have developed an intermittent fault of only finding the 1XRTT and not the correct EV-DO rev A , thus web pages don't load and are timed out .

Ive been to two separate CAT CDMA towers to check the modem, and the intermittent fault occurred at both tower locations , ive been to the CAT office to see what they think about the modem problem, my modem is an old version that has no removable SIM card, its just dedicated to one CAT CDMA phone number . They can offer me a Vertex VW140 USB SIM modem ( with external antenna connection that I need ) for 3,500 Baht . sick.gif

Ive been told by CAT that their 3G service should be in my area around March time ( possibly LOS time frame biggrin.png ) so I really don't want to spend a lot just in case I go with their 3G service some time in the future , the thing I'm now wondering is this, I all ready own a USB SIM modem that has an external antenna connection and has the following radio bands

3G/HSDPA/UMTS 850/900/1900/2100MHz

I know that the CAT CDMA uses these frequencies - 849Mhz ( up ) and 869Mhz ( down )

So could I use my own modem , and just get a CDMA SIM card from CAT , ive not yet put this idea to CAT .

would this work ?

any comments welcome wai.gif

No.

CAT seems to be ahead of schedule on 3G base station turn-ups so March could be February, or tomorrow?

from a recent article:

BFKT (Thailand) has been establishing a 3G cellular network for the agency faster than expected. CAT already has 4,000 base stations and now expects to have 14,000 by the end of this year. Earlier it had anticipated just 5,000 base stations in the first three years of the 3G roll-out deal.

Thanks , having been involved with CAT for years now , and my experiences at most levels when asking any CAT employees questions , I'm now never fully able to take what they say too seriously , I'm off now to the CAT office to meet an engineer rolleyes.gif , who has said he will test / check my modem, so the story continues .
