Hi, I happy to see this great upload with diassembed images and welcome on the board!
In Latvia there is CDMA 800 network?

Hello!
nice to be here and make this project better :) together we can!

My possesion with phone collection started "from inside" - "hobby" and full time work - mobile phone repairs .
So whats inside is so intriguing as all other feelin`s about collecting :mrgreen:
Lots of phones share same specs , but differs inside : chipsets , construction etc ..
or vice versa - different looks but same tech.
so , in my humble opinion , for preserving information about old phone this info is also essential.

cdma800 - nope , in Latvia there is no such network and newer was.
we have a cdma2000 (1x/EV-DO rev0/A/B ) operating on "old nmt" 450 Mhz frequencies ( Telekom Baltija with brandname Triatel )

this Zuma phone is one of my recent ebay purchase .
seller info states that phone was bought loong time ago somewhere in "other side of lake"
and sticker on battery tells "Vancell communications inc. ... " - Vancouver , Canada

Hi,
this is a perfect job for a mobile collector, or perfect hobby for a phone repairist :)
This cdma2000 operator is interesting, as I see it offers modems and tabletop
phones mainly?
The old NMT450 freqs in Hungary was teransferred to other services in 2003 when
Westel 0660 ceased its operation...

Peter

yeah , perfect , but hard to balance sometimes :lol:

Triatel won a tender from government to give wireless broadband to rural regions of country in 2010.
Yes , they did but ..
it was far more expensive compared to "usual" 3g/3.75g
rewievs from customers was mostly neitral than positive
promised 14mbps was rarely achieved ( rev B is not everywhere )
and about voice communications...
there was allways a small choice of phones ( in 21st century when everybody want`s a smartphones , cameraphones etc - you get kinda yesterdays phone at relatively high price , which even is bonded ( at least there was some time when it was bonded ) between devices serialnumber and r-uim card - that means to change a phone you must go to customer center and do paperworks ) and voice quality was ... better not saying anything :mrgreen:
maybe there was some improvements in last years , but train is already gone - there is no iphones or Galaxy`ies with cdma2000 @ 450 mhz = no customers , and seems that they abandoning "voice call" segment .

They ( Triatel ) also trying to cut that "mobile broadband" also for too-rural regions , as there is not enough customers
under lines : no more financing no more internets .

anyways - i think - cdma gets a hard times (agains ) - gsm/umts ir far more superior and already almost everywhere .
for example : for usual browsing and catvideos on youtube it is not diffrerence you sit on mobile broadband or 400mbit optics
( ok , ok , ping is bettter and 400 is 400 , but for "usual" as said before - it is no difference , even if you are in middle of forest ( peresonally tested : 3 from 4 rural places gives no problem with 3,75g ) )
and the big monster LTE ir already here ...
so we`ll see , we`ll see ..
