I never use iphone, and just try google search, seem iphone cannot set 2G only, i saw is 3G or 4G can set

Thanks for your reply.

When she first got her iPhone the 2G,3G & 4G settings were in her phone. After I setup her phone the 2G setting was gone so I can’t select 2G network in the future. This is the reason I raised a question here. We will wait and see how thing goes when 3G is terminated. Generally, she doesn’t need data plan as she is home on WiFi. She only been out of the house twice to get vaccinated since the pandemic.

Same question as above. What is your phone model and phone brand?

If you're using a phone that doesn't support 4G, then from next year onwards, your phone will connect to 2G network only.

If you don't use mobile data / did not subscribe to any data plans, then basically you can assume that the upcoming 3G network shutdown won't affect you. You will still be able to make and receive calls/SMS as usual, just like what you have today.

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).

Thank you very much for the explanation about 4G. I will shop around for new plans for my mom if she decides to ditch Maxis for another telco.

The list of Maxis 3G network shut down by state - https://www.malaysianwireless.com/2021/10/m...engganu-states/

Is it currently only maxis post schedule turn off 3G?
I still not survey what telco i need to switch, as my reply above,
My working place and my sleep room 4G very weak, i use 3G only, umobile

But the 3G spectrum will be back up again after mis-configurations at cell towers.

"Effective" shutdown is hypothetically by end of February 2022.

What do you mean? Elaborate further please?

Using Tim Team Apple summore... very malu if the cell towers are not configured correctly....also, be sure that we fully charged our devices as the battery will be depleted 50% faster than usual... this is becoz of the modem keeps on searching for the best LTE/EDGE signal all the time.... dual-SIM devices will suffer the worst....

they should shutdown the 2g too. because they will be blamed if users suddenly got their connection dropped from lte to edge.

if lte dropped to hspa it will not caused too much differences. but from lte to edge, u watch youtube 720p suddenly buffering to 144p.
