Start with the exact verification task, then establish whether you need continued access to the same number, which country and number types are eligible, who can see incoming messages, and how costs and delivery will work. Receiving an SMS is not the same as being accepted by a particular platform.
Short answer: work through format and country code, whether the number type is blocked, whether Apple actually sent the SMS, and whether your receive order is still live—before you keep swapping platforms. Even a successful bind does not mean you can re-verify later. For Apple ID and trusted phone numbers, prefer a long-term / reusable number you can keep receiving on; never use a public free inbox.
Short answer: CanSMS provides numbers and inbound SMS—not an official Claude or OpenAI channel, and not a promise the destination will accept the number. Match catalog project and country, choose temporary or long-term, and follow their terms.
Short answer: pick the country the destination is most likely to accept, then decide whether you need the number again. “Global” means multi-country capability—not unlimited stock or guaranteed verification.
Short answer: temporary for single checks; long-term reusable when re-verification, recovery, or binding matters. Cost follows reuse risk, not unit price alone.
