Hi everyone, I’m a old hippie wargamas, trying to understand this subject matter.
My wife has a very old Prepaid plan with PAYU. With 3G setting and mobile data setting to “off” she is able to stop the PAYU when she has no data subscription.
When the 3G network is removed at the end of the year, will all network settings be 4G because her phone doesn’t show 2G at the moment? Any idea? Thank you in advance.

I am also wondering the same thing as you.
in my case, my mom has an old post paid Maxis plan with no data. She already upgraded the sim card & phone but the network still say 3G.
Does 4G need data plan or what?
.
2G/3G and 4G LTE technologies are totally different and non-compatible. VoLTE(= Voice over LTE/4G) is like VoIP, ie more towards Internet technology for voice transmission of data packets through Fibre-optic cables.
2G/3G use the old Voice over 2G/3G and SMS technology = reliance on Fibre-optic cables is optional, ie not modern 4G VoLTE and IMS.
Voice over LTE = VoLTE , and ...
Text Message over LTE = IMS, not SMS.
So, 4G LTE cell towers need to be configured for VoLTE and IMS for the latest smartphones that have default setting of 4G LTE and/or 5G LTE. Maxis seems to have not done so. Celcom has = Celcom has been proactively shutting down 3G technology in many of it's cell towers after having configured them for VoLTE and IMS.
YES celco only has cell towers transceiving on 4G LTE frequency Bands, ie no 2G/3G = all it's 4G LTE cell towers have been configured for VoLTE and IMS, ie no Voice over 2G/3G and no SMS = YES subscribers must use modern smartphones with VoLTE and IMS.
OTOH, both 2G/3G(= Edge/HSPA+) and 4G LTE technologies can use Internet data but at different speeds, eg 4G LTE gives normal speed of about 30Mbps per frequency Band. Hence, all cell towers have backhaul connections to the HSBB Fiber Internet network, eg the celcos pay TM HSBB Wholesale about RM90 per 30Mbps bandwidth = RM9 per 3Mbps. Hence, Maxis Hotlink Unlimited Prepaid is priced at RM35 for 6Mbps.

@ HippyTony, ....... If the iPhone cannot use 2G frequency bands, once 3G is shut downed, your wife may need to change her prepaid plan to use 4G LTE, VoLTE and IMS.
@ wkn, ....... Afaik, most phone plans have separate charges for voice-calls, text messages and Internet data. Maybe you only need to shop around for the right new plan for your mum, eg Yoodo(= MVNO riding on Celcom's network).
