Use cases
Keeping your number out of every signup form
Who this is for
Anyone who has ever bought something online
Quick answer
The problem
Retailers, delivery apps, loyalty schemes and marketplaces all demand a phone number to function, then leak it in the breach they have three years later. Your number becomes the join key that links every one of those records to you.
What to buy
Keep one long-term line and use it as the contact on every commercial account. That line absorbs the spam, takes the breach hits instead of your real number, and when it becomes unusable you rotate it. Nothing important breaks because the second line only does commercial duty.

Source contact for journalists and researchers
A contact number that resolves to your identity puts sources at risk, not just you.
A recovery number that is not your main one
Using your primary number for account recovery makes SIM-swap attacks catastrophic: one social-engineering call to a carrier support desk…
Testing SMS flows across countries
You cannot test international SMS delivery without international numbers, and buying SIMs in nine countries is not a realistic engineering…
