Just to share what i am aware.

With Unifi Air (band 40, with 4G router modem), speed test 20 - 30Mbps, while watching youtube with phone, the resolution auto to 360 and I couldn't change it.
On Unifi Mobile (band 40, subscribed to weekly RM20 unlimited LTE, 4G router modem) - speed test 7-10Mbps. Youtube resolution auto to 360 too.

Both scenario at same location, same modem.

You need to make the supplemental lines become principle line, then only allow to port out.
If all your lines is principle, then no problem to port out. This is the problem when you have supplemental line but would like to retain the number and port to other telco. Another method is port the supplemental line to hotlink prepaid, then only from port Unifi Mobile/BEBAS later.

The new Hotlink unlimited look promising. Definitely aggressive move by Maxis. I think later Celcom / Digi will follow the path....

It's RM38 (promo 35) and RM48 (promo 45), and those info available in TnC page only. Maxxx always like to hide detail.

Thank for the great sharing. Please share more on consistency of the network and experience of 3Mbps to watch youtube. I guess 360p should be good with 3Mbps.
Later Maxxs found their network congested, then they may quietly amend TnC like... capped to 10GB per calendar month or etc.

Yes, sharing same network. It's said will tag along Maxis for 4G coverage. Anyway, most of outdoor coverage have no issue, and get 5G for city areas. Major concern is malls basement or inner/corner end of building where no coverage....

I have a question too, whether unifi mobile already integration Maxis 4g for coverage or still work in progress? Anyone know about this please share. Thanks.

Mind to share how we could know we are connected to Maxis 4G? So far i able to see it's shown uni5g string and either LTE or 5G.. thanks.

I don't have problem on voice call for unifi mobile. It's shown volte but i didn't verified whether calls in volte. Anyway, previously having problem with unifi mobile that it's not allow to make call untill I enable the international call function. The local call with +60 make it think an international call...

I tried manual select the operator from phone settings, just showed up uni5g and cant see Maxis in the list anymore.

Good day to all.
If now i get a old sim card from seller for credit never expired and activate it, do i still enrol for previous prepaid plan or new wow prepaid plan?

The new unifi mobile prepaid wow plan with top up for active day make it no more attractive.

Or any good alternative that low cost to keep other then hotlink prepaid with very low usage on data and call.

Thank for the tips and info.
Yeah, the bebas plan the best, and now only old batch of supporters got to keep that plan.

Thank alexgoh2.

If the seller able to provide registration to old bebas plan, please pm me. Random number will do for me. Left 1 line to fill up my max 5 quota.

I am having problem with some of my data quota before the migration too. It's not usable and end up I need to buy the RM18 for 8GB.
Those old data still stuck in the account, can see, cannot use.

Anyway, I got 2 different accounts type. The Bebas 10 can use the data quota, but not the "mobile unifi" plan. Going to trial again after finished up the 8GB and see those old data quota is usable.

I have the RM18 8GB for 4G/5G, and saw the RM3 for 15GB 5G, bought it...
The straight thing is.... it's didn't auto deduct my 5G data usage from 15GB 5G (1 month) but deducted from my 8GB 4G/5G (no expired) quote. This make me feel like kena trap. The system should auto deduct from time limited data plan.

Having the same problem too, wasted the money.
Now I stick to finish all the carry forward data, before any new buy.
