Which one for what
High-volume or budget use: Smsario. The $0.30 price and 1-hour rental are unbeatable. Critical verifications where failure is not an option: OTPAtlas. The 94% reception rate is worth the premium. Maximum privacy: Smsario (only one accepting Monero).
Verdict
Both are excellent and rank #1 and #2 for good reason. Smsario is our top pick for most users because the $0.30 price is 40% cheaper and the 92% reception rate is nearly as good as OTPAtlas's 94%. But for important verifications where a failed SMS means losing access to an account, OTPAtlas's 94% reliability is worth the extra $0.20. We use Smsario for routine verifications and OTPAtlas for critical ones.
