Choosing an SMS provider might seem straightforward, but the differences between providers can significantly impact your delivery rates, costs, and customer experience. Here's what to look for when evaluating your options.
1. Direct carrier connections
The most important factor in SMS delivery is the route your message takes. Providers with direct Tier 1 carrier connections deliver messages faster and more reliably than those that rely on aggregators or grey routes. Ask your provider: do you have direct connections to UK mobile networks?
Direct routes typically achieve delivery rates of 97-99%. Aggregated routes can be significantly lower, and grey routes — while cheaper — risk messages being blocked entirely. For businesses sending time-sensitive messages like appointment reminders or security codes, direct routes are non-negotiable.
2. Transparent pricing
Watch out for hidden costs. Some providers advertise low per-message rates but add charges for:
- Inbound messages (receiving replies)
- Dedicated numbers
- Delivery reports
- API access
- Monthly platform fees
The best providers offer clear, all-inclusive pricing that covers the features you need. Ask for a full breakdown before committing. You can view our transparent pricing to see what genuine all-inclusive SMS pricing looks like.
3. UK-based support
When something goes wrong — a message isn't delivering, a campaign needs stopping, or you have a compliance question — you need to speak to someone who understands the UK market and regulations. Offshore support teams working from scripts rarely have the expertise to resolve SMS-specific issues quickly.
Look for providers that offer phone support during UK business hours and can provide a named account manager rather than routing you through a ticket queue.
4. Compliance and fraud monitoring
Your provider should be ICO-aware, GDPR-compliant, and actively monitoring for fraud. This includes AIT detection, smishing prevention, and opt-out management. Ask what fraud monitoring is included as standard versus what costs extra.
A responsible provider will also help you stay compliant with PECR regulations, manage opt-out lists automatically, and provide audit trails for consent management.
5. Integration options
Consider how you'll connect. A good provider should offer:
- REST API — for developers integrating SMS into applications via a robust SMS API
- SMPP — for high-volume enterprise connections
- Email-to-SMS — for sending texts from your email client without any coding
- Web application — for teams without technical resources
The right provider offers multiple integration paths so you can choose what works for your team today and scale into more advanced options as your needs grow.
6. Scalability
Your provider should be able to grow with you. Check throughput limits, whether pricing improves at higher volumes, and whether the platform can handle traffic spikes without degradation. Ask about load balancing, failover systems, and whether the platform has handled volumes similar to your projected peak.
7. Reporting and analytics
Visibility into message delivery is essential for optimising your communications. Your provider should offer real-time delivery reports, exportable analytics, and dashboards that show delivery rates, response rates, and cost tracking. Without proper reporting, you cannot measure ROI or identify delivery issues before they become serious.
Frequently asked questions
What is the difference between Tier 1 and aggregated SMS routes?
Tier 1 routes are direct connections to mobile network operators (EE, Vodafone, Three, O2). Aggregated routes pass through intermediaries, adding latency and reducing reliability. Grey routes use unofficial channels that risk messages being blocked.
How can I test an SMS provider before committing?
Most reputable providers offer a free trial or test credits so you can evaluate delivery speed, reporting quality, and support responsiveness before signing a contract. At Faretext, we offer 25 free credits when you register.
Do I need an API to send business SMS?
No. While an API offers the most flexibility, many providers also offer web-based applications and email-to-SMS gateways that require no technical knowledge at all.
What delivery rate should I expect from a good SMS provider?
A provider with direct carrier connections should consistently deliver 97-99% of messages. If a provider cannot share their delivery rate data, that is a red flag.
At Faretext, we offer all of the above — direct Tier 1 carrier connections, transparent pricing, UK-based support, comprehensive fraud monitoring, and multiple integration options from API to code-free web application.
