"Marketing page, not a contract" marks an uptime figure the provider prints on a product or marketing page with no service level agreement behind it on the pages we read; each figure links to the page it was read from. The month is the published list price: enterprise contracts are negotiated, and no provider here publishes its negotiated rates.
Every provider here is scored on the same six criteria on the best SMS gateway providers. Ranked by developer documentation, the SMS APIs are compared on the best SMS APIs, and by price on the cheapest SMS APIs. A month of bulk sending at any volume is priced on bulk SMS providers.
