Jio has pan india spectrum in band 40 - 2300Mhz. It also has Band 5 - 850 Mhz sharing with Reliance. It further acquired in auction band 3 - 1800 Mhz in some circles. If Jio's 4G for Reliance CDMA upgrade customers is deployed on band 5, it will also deploy 4G in band 3 & 40. Otherwise what Jio will do with spectrum in band 3 & 40? My proposition is that a 4G handset with band 3 support should work in some circles & with band 40 support should work in all circles for data. (VOLTE will depend on handset support). Handset without VOLTE support should also work for voice as Jio has Pan India agreement with BSNL & Reliance Communication for 2G/3G voice fallback. So the conclusion is, All handset with particular deployed 4G band in respective circle but without VOLTE will latch on either BSNL or R COM GSM network for voice All handset with particular deployed 4G band in respective circle but with VOLTE will use Jio data network for Voice & will switch to 2G/3G voice fallback where Jio coverage ends. Is my understanding correct?

Hope that clarifies.Whatever backbone JIO may be developing, the reality is that their commercial launch is being delayed just because of their unsuccessful VoLTE testings. So JIO cannot think of providing voice fallback for RCOM 4g customers. Chances are very high that JIO will use RGSM and their ICR partners for its voice fallback even after successful VoLTE launch. Lolz. OK, so at least you got the point that LTE is in fact GSM for layman. There is nothing wrong with VoLTE technology used by JIO. Their VoLTE testing has been successful wherever their towers are operational. It is more to do with lack of VoLTE enabled handsets with the mass public and lack of full penetration of their towers that will force JIO to look for other partners for voice support and that too for the time being.

What happens to Wireless landline phones? As far as I know they use the same CDMA network which they are 'upgrading'. We have 2 such connections.

Till they shift junk of the Customers to R4g they won't be able to shut down cdma Buy they may trouble cdma customers with poor netowrk and slowly bringing all to 1x and compelling all to move to 4g So people willing to stay on cdma should not opt 4G sim Sent from my iPhone using Tapatalk

What plans are on offer for RCDMA users migratign to RGSM? Migrating to RGSM is completely different than upgrading to 4g. You have to do MNP/INP to migrate to RGSM and the plans are not very attractive too. Better upgrade to 4g and ur same voice and data plan will continue. You can use the 4g sim in normal 2g/3g gsm handset also if you dont want to use 4g. Post 90 days you will b eligible for MNP once again. What do u mean by 4G is different than RGSM here? Are you saying that CDMA customer who upgrade to 4G will have different network than RGSM? I thought even RGSM customer can use 4G network Reliance CDMA migrating to 4G will NOT use Reliance GSM network at all. They will solely use JIO's LTE/GSM network.When did JIO put their gsm network ??????. They only have their own LTE network and for voice they are still struggling with VoLTE.Sent from my ASUS_Z00AD using Tapatalk JIO's LTE network will be known as GSM for the general public for all sense and purpose. It will use 4G enabled phones with LTE bands which are all basically GSM phones not CDMA. Reliance's GSM network is pathetic to say the least and the voice fallback plan for Reliance 4G customers is suspect and JIO is developing it's own backbone over LTE and VoLTE to counter that. Hope that clarifies.

Everything correct except the price of the sim. Its ₹25.

4g will be launched very soon in the above 10 circles and cdma services will not continue there after 31st May. Only cdma customers will be upgraded currently. GSM customers will have to wait. For upgrade to 4g all customer has to do is purchase a 4g ready sim and send a sms from his no along with the 19 digit sim no. MNP/INP not required. LTE will b used only for data and fallback of voice will happen on 3g/2g automatically.
