Any device recommended for digi infinite 150 with CA ability?
From 1st page and the this forum, i saw there are 3 main category for digi i150 such as modem, mobile hotspot and phone to insert the digi sim.
Modem I saw Huawei 525 and 5186-22a and huawei b618 are popular and good.
Pros:
Having more stable internet if compare with mobile hotspot.
Cons:
Need purchase other phone to connect with the modem for calling. (plug-in)
Mobile hotspot I saw netgear ac790s is in the list for Carrier aggregation(CA)
Pros:
Can bring and carry to it anywhere for surfing internet. (Balik kampung during raya and outstation also can bring along) (just can sharing internet and some model can act as powerbank)
Cons:
Less stable internet if compare with modem router.
Cannot calling from anywhere (cannot act like smartphone & Wasting the unlimited call)
SmartphoneFrom 1st page only shows Samsung high-end phone such as S7 and S8 have CA ability.
Pros:
Can call from anytime and anywhere.
Can bring and carry to it anywhere for surfing internet and act like mobile hotspot
but with more function (act as spare phone, driving recorder, entertainment and so on)
Can insert one more sim card if u pick dual sim phone. (Calling from others to my old number and new digi i150 number can always be reached)
Cons:
Less stable internet if compare with modem router.
Device easily get hot. (But i think it won't explode and burn like note 7 right?)
Conclude:
I will pick Smartphone.
The reason i pick the phone for digi i150 over modem and mobile hotspot is because it act like a all-rounder which can overcome all the pros from modem and mobile hotspot without scarifying all cons too.
Although without the top speed and telco tower congested during peak hour, as long as still can connect the internet is okay for me because i not the advanced user. So, i think the less stable internet is not issue for me.
After doing some finding:
S7 and S8 are quite expensive which around and more than 2k.
I think the cheapest we can get for 3CA device is lg v20 H990DS ?
removable battery + unlimited call
removable battery can swap battery (3200mah) easily just like a mobile hotspot
unlimited call can enjoy the call anywhere (which currently all the mobile hotspot cannot do)
Can insert SD card to be storage purpose.
Sorry for long post, hope all the lowyat forum-er can give some advise to me before i purchase the LG v20 with 1k++.
Kindly brave to share your thinking too if i missing out some point.
Thanks.

You'd kill the battery in no time. If u were to use it as mifi everyday.
