Yoola SMS pricing for South Africa
South Africa SMS costs 5 credits per SMS. At Advanced tier (UGX 25/credit), each SA SMS costs UGX 125 — much cheaper than Twilio's rates for the same routes.
ICASA and POPIA — the compliance you must know
ICASA (Independent Communications Authority of South Africa)
- Sender ID registration required for branded SMS
- Promotional SMS restricted to 8am-8pm South African Standard Time
- Opt-out mandatory and must be honored within 24 hours
- Content restrictions on political, religious, and financial promotions
POPIA (Protection of Personal Information Act) — South Africa's GDPR
- You must have lawful basis to process phone numbers (consent, contract, legitimate interest)
- Privacy notice required at point of data collection
- Cross-border transfer safeguards required (relevant when sending from Uganda to SA)
- Data subject rights: access, correction, deletion, opt-out
- Penalties for POPIA violations: up to R10 million or 10 years imprisonment
If you send commercial SMS to South African numbers, POPIA compliance is not optional.

Important: 10DLC and sender ID rules
Unlike Uganda's simpler system, South Africa has strict rules:
- Alpha sender IDs must be registered per network
- Short codes require significant setup (typically 6+ weeks and R50,000+ initial fees)
- 10DLC (10-digit long codes) available for lower-volume senders
