The report card
Best for prepaid bulk SMS without a subscription
BulkSMS sells prepaid SMS credits with a web platform, an API and two-way numbers, valid for 2 years. But there's no price list, only an estimator, and the number of credits per message changes by network, so you don't know the cost until you ask.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No fixed price is published. Credit packages run from 200 to 50,000, but the pricing page is an estimator and the credits a text uses vary by network. |
| Free plan and trial | F | Nothing free. A money-back guarantee on credits isn't a trial. |
| Features | C | A web platform, SMS API, incoming long numbers and shortcodes, plus RCS and WhatsApp. Larger volumes are a quote from sales. |
| Ease of use | C | No store rating on record. Sending from a web account is simple, but the API and number set-up take work. |
| Platforms and integrations | C | Web only, with an API but no integrations listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who BulkSMS is for
- Fits if you send bulk texts now and then and don't want a monthly plan
- Works for developers who need an SMS API that covers many countries
Who it is not for
- Not for you if you want a clear price per text, as costs are only estimates until you ask
- Watch out: the credits one SMS uses differ by network
- Pricey if you send in large volumes, since those are quoted by sales
- Skip it if you want a free trial, as only a money-back guarantee is offered
Good to know
Good for
- Businesses that send occasional bulk SMS without a subscription
- Developers adding SMS to an application through an API
- Teams texting across many countries
Worth knowing
- The pricing page shows an estimator, not a fixed price list; the cost per message depends on destination network and credits used.
- The number of credits per SMS varies by network, so message costs are only estimates until you ask for a quote.
- Larger volumes are priced through a quote from sales.
- Customers in South Africa contract with Celerity Systems; others with Celerity Messaging UK.

What it costs
Every plan, the free plan, ways to pay less and how prices have moved
BulkSMS's current pricing could not be confirmed from its own site.
A money-back guarantee on credits isn't a trial.
We could not confirm BulkSMS’s current prices from its own site, so this guide lists no plans. bulksms.com has them.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace BulkSMS you would be making texts to thousands of numbers, registered with the carriers. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 62 of the 77 other SMS and chat marketing tools grade higher.
What you could not
- Texts to thousands of numbers, registered with the carriers.
- The WhatsApp Business API, which Meta opens only through approved partners.
- Texts from a business number, registered with the carriers.
- An API that other software can build on.
What this rests on. BulkSMS’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
