Hello there,

Yes, you can subscribe item 2 + item 4 and still get the free 10gb monthly data plan.

Thank you.

How is it now? If you didn't manage to topup RM10 within 24 hours (to get 28 months validity) of activating your new SIM due to the downtime, I suggest you call them and let them know, I think they'll give you another chance to do so, since it's their problem earlier today.

Some people are quite unlucky to get their simcards today (or, like my friend, just successfully MNP to onexox today and experienced such a fairly major downtime right away). A rather bad impression for newcomers if you ask me. 

MNP online or brick-mortar kiosk?

Ported my 2 lines from Hotlink Sabah 1.0 over to 1X-22. Kinda regretted after using for only a week

OneXOX didn't stated 1X-22 data speed. It just stated "High Speed".
1X-22 data speed: High Speed
1X-35 data speed: 50GB @ High Speed, Unlimited @ 10Mbps
1X-48 data speed: 150GB @ High Speed, Unlimited @ 10Mbps

Can see phone on 4G and 4G+ full bars. However, the loading speed is not up to the standard kinda worst than hotlink (shopee app, fb wall feeds, not even youtube). 
Question: What data speed 1X-22 actually is? (Kinda gimmick to lure new port-in)

As for comparison, other telco clearly stated the data speed. (Btw, both are not MVNO of celcom)
Hotlink RM25 40GB data speed 12Mbps
U Prepaid 25: Unlimited data at 12Mbps

redONE ULTRAplus25 100GB of high-speed 5G/4G data (under Celcom network, no data speed)

I guess cheap for a reason. Coverage is there but data speed is throttle (I guess between 6-8Mbps).
Perhaps, the actual data speed we getting is just the same as 1X-18 data speed: 6Mbps   

And there's one saying "if you pay peanuts, you get monkeys"   

Errr.. I think it is because you don't have 5G. Have you activated 5G?
I can easily get 300-400Mbps on 1X-22.
