For loaded systems, the absence of sudden blockages due to changes in the provider's tariff policy is critically important. Choose companies with a transparent, fixed volume of daily packages and a stable connection processing speed. Before signing the contract, be sure to check the gateway's performance under a moderate test load.

Our service provides analytics to developers, and the stability of incoming channels is in the first place for us. After several failures with the free aggregator, we switched the entire architecture to https://billing.meteoprog.com/informer, having previously tested the queries in the test area. The limits turned out to be quite predictable, and the response rate was stable around the clock. During several months of operation, no server crashes have been recorded, and we plan to extend the contract.
