Changing Phone Carrier To?

Hello redditors. Just want to get your opinion and suggestions.

We currently have 3 mobile plans and an internet for the house with AU. Services were great in general.

But we decided to downsize and switch to a cheaper provider.

I have been seeing Ahamo and Rakuten, but I could not understand how their plans work.

Wife and I are constantly traveling on a daily basis because of work so we need the unlimited internet. We tried the 30GB plan with UQ but 30GB is too small for me and I would normally use it within 10-15 days. The reason for that is our sidejobs requires uploading and downloading projects.

Can I get suggestions?
