Why the number matters
People in Portugal reply to, and call back, the number they see. A sender name cannot receive replies, and services that do not use your SIM give you a new number to rent, so customers see a number they do not know.
Accents in Portuguese
DroidSender counts messages, not parts. At services that charge per segment, an emoji or an accented letter like á, ó, ç or â limits each SMS to 70 characters, so a 100-character text counts as 2 SMS instead of 1. How SMS length works
Portuguese uses ã, õ, á and ç all the time, so at those services most messages in Portuguese are counted at 70 characters per SMS.
Which one fits
- DroidSender: small businesses that already text customers from their own phone and want campaigns and a shared inbox on the computer.
- Invisible Cloud: a Portuguese company with a custom sender name, sends of up to 10,000 SMS a minute and payment by Multibanco or MB WAY. Two-way works through a virtual number you rent.
- Twilio: developers building SMS into their own software, with a carrier-grade API.
- Bird: businesses that want SMS, WhatsApp and email in one free inbox, paying for each message.
