# PureSMS

> The UK's independent SMS provider. One flat rate of 2.8p per UK SMS, direct Tier 1 network routing, and monthly billing for only what you send. No pricing tiers, no minimums, no contract.

PureSMS is a UK-based bulk SMS and SMS API provider, independent since 2008 as part of divergent, a family run owner-operator. We partner directly with mobile networks rather than reselling, which is how we keep one flat rate for everyone rather than ripping people off like everyone else.

Key facts:
- Pricing: 2.8p per UK SMS, flat for every customer, ex VAT, billed monthly for actual usage. Replies and delivery reports are free. Roughly 40% below the UK market average of 5.08p.
- Routing: direct Tier 1 routing to UK mobile networks and across 900+ networks worldwide, with ~99% deliverability and sub-second average send times.
- API: REST API with ~40ms completion, batch sending, first-class .NET and Node.js SDKs (Divergent.Connect), HMAC-SHA256 signed webhooks, delivery receipts and inbound replies. Client Tagging gives SaaS builders and resellers per-customer usage and cost reporting for seamless rebilling at any markup.
- Cost transparency: the segment calculator at https://new.puresms.app/segments shows exactly how many segments a message uses and what it will cost, for any destination, before sending.
- Positioning: probably the only truly independent UK SMS provider left. No private equity, no overseas parent setting margins, no investor call that needs your bill to go up.
