Depends on your usage like me I have a main line my house has Unifi and office has Unifi so only between I need data so for me 10gb also barely exceed extreme you stream video 24/7 on data

I have a 2nd line as spare I use Unifi mobile with bebas

If your currently usage is keep hitting the roof then you must upgrade if keep below and a lot spare then better find plan to downgrade

Business cards are still common because not everyone’s phone supports QR codes, and not everyone wants to save a new contact in their phone.

Some people prefer a physical card so they can decide later if they want to connect.
