In short, I need long validity with little data at minimal cost. Calls can be PAYU. She’s currently on TuneTalk with one year validity and no active data plan expiring in January. Hence, I’m looking for a better option now. I have no idea why this TuneTalk will deduct her credit a few cents on daily basis when she’s connected to WiFi. Probably this Hotlink Pantas is not too bad.

I have also checked XOX and thinking to MNP her no. there, 28 months validity and buy season pass of 10GB for her, then subscribe to monthly 500MB which can last 20 months.

Not sure if I can have better/easier options here.

The 365 days Active Period pass is priced at RM30 and can be purchase from your Hotlink app. By activating this pass, your account/ SIM will be active for 365 days (1 year) from the day of activation/ purchase. This means you do not have to constantly top up to keep your account/ SIM active.

So means, data transmission for CCTV (download/upload) only consume VERY LITTLE data (~20-50MB per CCTV @ 1080P resolution).

In the FAQ, in order to need to be active, i need to do out going call, SMS or BROWSE INTERNET. Browsing the net could consume anywhere from 100MB to ~1GB, depending on sites, especially those that have many multimedia contents in it?
Since my CCTVs just operate on an old chapalang TPlink MR200 4G Router with Hotlink Pantas in it, i guess i HAVE to topup minimum RM10 for every 60 days. 

God demyuhh Maxis! 

Appreciate your technical insights in this matter azhar75

As you can see, the 20GB with 365 validity will end on 18 Feb 2023, but yesterday my line was rendered INACTIVE due to i didn't do outgoing calls,sms or browsing the net. Thus, i had to reload minimum RM10 to keep my line active for the next 30 days. 

so the way i see it, in order to keep my line active is either i need to:

topup rm10 for every 30 days for the course of 365 days - RM10 per month x 12 = RM120

OR

within that 30 days, i need to connect to the 4G router and occasionally browse the internet, maybe watch a youtube video or two.

my CCTVs are for monitoring my workshop and my office is a bit far from that. that's why i do such setup.

so in conclusion, i can say Hotlink Pantas is not really suitable to use for CCTVs operation via 4G router.
but if you use in your smartphone, no need to topup min RM10 for every month.
