Information given by tower engineering personnel on 21/05/2016 for Gujarat: "No information given by infrastructure / MSC department to modify CDMA signal or shut down bts temporarily or permanent. No instructions for gain control or horn adjustments or aperture leveling. No messages from switching centre" But it is possible the entire changeover will happen at MSC and current CDMA bts not involved in the upgrade process. While the process of shifting MDN/MSID in msc has started, cdma will not close today or tomorrow. Also the rumors of 3 day blackout in the cdma network is not given by infrastructure department so it might not happen. Subscribers who have not taken 4G upgrade (more than 60% users in Gujarat still on RCDMA) will continue on Reliance for the next two weeks. Before Reliance shuts down it's own CDMA, it will/may/can silently transfer users to MTS for 1X connectivity only. EvDo Rev A/B is not likely post MTS shifting. MTS was using 1X Reliance for voice calls in GJ since many years so this technology usability is not difficult to achieve. Reliance has been changing it's policy quite often during this month. It is also likely RCDMA will continue and 4G will be provided using MTS spectrum. Major factor is the subscribers' willingness to switch over to 4G. Assuming there will be no CDMA within a week but users can still obtain mdn specific port code from Reliance store from their UI. The option to upgrade to 4G from their system is even after total close down. Users can still port out once their 4G sim is operational. Just as Hetal bhai mentioned about CSFB to be used in RCOM 4G, it would have been a wonderful technological breakthrough if it was 1XCSFB as upgrade. CDMA is not a legacy technology, Rcom did not want to invest more in CDMA, they wanted 4G for GSM and with minimal capital investment. The most viable solution given to them was to liberalize CDMA and use the same infrastructure for cheap 4G. Even after shutting down their own CDMA, they can still provide 1XCSFB in MTS states with LTE routed to the new Rcom 4G. Sent from my K016 using Tapatalk

I bought ZUK Z1 I inserted my cdma sim not supported. after i found model no z1221 is same model selling in china.i figuring out from various blogs and forum flashed chinese firmware on my zuk z1.after flashing now i got cdma working with EVDO.i added the screen shots.but network speed is not good.may due network update.

I have a box of Khandvi ready...;)

Reliance com. is requesting all CDMA customers to opt for 4G upgrade from last 20-25 days. Each time they are saying that the 4G upgrade will commence in next few days. They are not committing themselves as to exact date of commencement of 4G service. i was told by an R Com executive that once you put in an upgrade request you cannot port for 90 days. Once R Com gets significant numbers to put in upgrade request JIO will launch its 4G network. Those who have put in upgrade request will not be avail any better offer from JIO and other operators. Please put in upgrade request only after R Com has started its 4G services.

Just parking some weekend thoughts here about this whole CDMA / GSM / 4G thing. Netconnect users (prepaid) would remember that recharge tariffs went up in late March or early April this year. For some years, I was able to recharge for Rs 797 and get between 5-10GB usage. Now, to get the same, I have to recharge for Rs 1299 or so (this relates to Mum/Mah circle, so your values may be different). Now remember that, in March/April, no one really had a clue that CDMA was going to be shut down or 4G was going to be launched "soon". In the former case, people were still buying CDMA handsets and news about 4G launch was still something that was several months away. Adding the two, it's obvious that something was cooking. Instead of telling us that CDMA was on its last legs, or that they were testing a new network for a "proper launch", the very first thing Reliance did was raise tariffs on data. Also, their emphasis seems to be more on pushing 4G handsets than talking about the 4G network. This is like putting the cart before the horse. In both cases, Reliance gets money, whereas we keep waiting for dates like 31 Dec, 30 Jun, 31 May, and then now, it seems like 24 May. Given this background, I remain sceptical about 4G. After all this hype and doubt, what if they finally pull the curtains to reveal something that says 4G on the box but runs more like 3G or 2.5G? If they're building 4G services by adding on to legacy networks then performance will be patchy. Moreover, in a professional launch, we usually see articles from independent beta testers and other qualified experts who are given a glimpse of network quality (pros, cons, progress, things like that). Add to that, all of the publicly available reviews are for handsets, not the network itself. So this whole launch process is running behind the scenes and all we're getting are bits and pieces of information from "dealers". Hopefully, by 24 May (or is it 3 Jun?) we'll get more clarity. Till then, I can just hope that CDMA continues to function and the migration is free of unwanted drama and suspense.

Not now....

Hi all, Looking at all the happenings .My observation and my understanding is ......... Thing logically Point No.1 - We are seeing the JIO struggling to test their network for years and not yet completed their testing the network IDEA and AIRTEL took months to test their network........ Now RCOM has not started testing their 4G network.Because to test the network they should have network and they will have network once they have spectrum.Yes they do not have spectrum ready and they get the spectrum once they shut down CDMA services and same spectrum is been planned to use for 4G services.Still we are using CDMA services means they their 4G network is not ready for testing forget about commercial launch. Once they shut the services they may need few months to test their 4G network. In reality how many months(years) they need to test the network we can easily guess based on their GSM services launch in 2009.We know very well the efficiency of RCOM and Mukesh Ambaniji. Point No.2 - What Rcom's Plan might be ? . They want all the CDMA users to shift to GSM services. They are shifting the CDMA users in the name of 4G upgradation and some free benefits and also by creating the confusion and finally FEAR among the users.If RCOM asks the CDMA users to shift to RCOM GSM no one will shift rather port out to other operators.Once CDMA users are shifted they will be on RCOM's GSM network(3G network which ever circles available and just 2G network where 3G is not available) untill they test their 4G network(after shutting down CDMA).For testing how many months/years they will take dont know.Till then they keep on declaring date(unofficially) and keep on postponing( how we are all waiting for JIO for years).It may launch finally after taking its own time. Point No.3 - Even if Rcom wants to launch 4G overnight within hours of shutting down CDMA services without testing the network, We can imagine the quality of their network and efficiency of their staff in handling the huge number of complains that will be poured upon. This is my understanding. You all can have your own understandings Thanks
