Frequently Asked Questions
What is A2P SMS?
A2P (Application-to-Person) SMS refers to messages sent from a business application to a mobile phone. This includes transactional messages like order confirmations and OTP codes, marketing campaigns, appointment reminders, and notifications. A2P SMS is different from P2P (Person-to-Person) texting and requires a business messaging provider like SendSeven to send at scale.
How much does business SMS cost?
SMS carrier costs vary by destination country and are billed at cost via prepaid credit, with no markup. On top of that, SendSeven plans start at Basic (€49/month) with unlimited users, no per-seat fees, and a monthly message bundle included; higher tiers (Professional, Scale, Enterprise) add AI, automation, and lower per-message rates. Developers who only need API access can start with API Only from €9/channel/month. Every plan includes 100 test messages in a 14-day free trial to get started.
What is the SMS character limit?
A standard SMS message is limited to 160 characters using GSM-7 encoding. Messages using Unicode characters (such as accented letters or special symbols) are limited to 70 characters per segment. Longer messages are automatically split into multiple segments and reassembled on the recipient's phone. SendSeven handles message segmentation automatically.
Is SMS GDPR-compliant?
Yes, when handled correctly. GDPR requires explicit opt-in consent before sending marketing SMS, easy opt-out mechanisms, and proper data handling. SendSeven provides automated opt-in and opt-out management, STOP keyword processing, consent tracking, and EU-based data processing to ensure full GDPR compliance for your SMS campaigns.
Can I send bulk SMS?
Yes. SendSeven supports bulk SMS to thousands of recipients simultaneously. You can segment contacts by tags, location, or custom fields for targeted campaigns. Features include scheduled sending, personalization with dynamic variables, delivery reports, and link click tracking. Combine SMS with WhatsApp for maximum reach. All bulk messaging requires proper opt-in consent per GDPR regulations.
