Follow-ups
What will my mobile plan charge for 1800 calls?
Ask your carrier or read your plan's Critical Information Summary — many plans include calls to 1800 numbers under the standard allowance, others charge them.
Why the distinction between fixed lines and mobiles?
Because the toll-free guarantee is defined for the fixed-line network, while mobile charging is carrier business that varies by plan and changes over time.
Does the business pay for my call if I use a mobile?
Yes — the carriage cost lands on the business's 1800 plan regardless of what you dial from, charged per second.
Is dialling different from a mobile?
No — ten digits, no area code, identical sequence. The full dialling guide is in how to call an 1800 number.
