You’re way overpaying. I pay $40 for 1.5 Gbps with Bell FTTH. Give them a call and say it’s too expensive and see what they can do for you. Or tell them Rogers (if they’re in your area) offered you 1.5gbps for $60 and ask if they can beat that.
As for mobile, you should look at new plans. $39 gets you 20 GB $50 gets you 40 GB. Seems like plenty of data imo https://www.koodomobile.com/en/rate-plans?INTCMP=KM_HDD_2023_Plans_RatePlans_40gbfor45_ROC_MBSK
Best time to get a mobile plan is Black Friday, should be even better deals by then.
You shouldn’t need a business line to get reliable, fast, unlimited internet.
