'Why do I my outbound SMS from Plivo not work when they work with Twilio?

I've been using Twilio to send SMS and things work great. The only issue is that Twilio charges for both outbound and inbound messages. As such, we've been looking for other solutions.

We thought we found it with Plivo as their pricing was more favorable for SMS.

However, with Plivo, very quickly our outbound messages are being marked as spam or something and they're not being delivered.

We are sending the exact same message every day to about 5k users at a given time in the day. The message has a url in it, but it is something our users signed up for.

Two questions: 1. Why does everything work on Twilio and not on Plivo? 2. Is there a code change I can make to ensure our outbound messages sent with Plivo are not marked as spam by carriers and then stopped?

You need to contact Plivo about this. I experience this problem too. Their carrier mark our number as spammer since we are sending almost the same messages (verification). They called their carrier and our number was white-listed.

Plivo Sales engineer here. This is indeed an issue with the carrier marking your messages as spam. We can definitely help you overcome this. Could you please drop an email to ramya(at)plivo.com and we can sort this out?

You need to contact with Plivo support , there may be problem for number prefix for country like if you are using twilio you have to add +(with country prefix) but not in Plivo. It will be better to contact with Plivo support.

Thank You

I dont know how Pilvo work but usually with SMSC there is Message Queue associated sometimes with each SMPP Client and also with Mobile Station. You can't always send messages until your certain number of request are still pending. there is a specific error code that SMSC sent to its client about message queue overflow.

BADABING BADABOM! After having a look in the Plivo administration I noticed a new option under other-settings "Automatic Encoding Of Unicode Characters". As Norway uses inernational characters this is definately a setting for me, and after enabling it all SMS are delivered as expected. So remember to enable this setting.

MAKE SURE TO ENABLE THIS:
Path: Plivo admin / Messages / Settings / Other settings
Feature: Automatic Encoding Of Unicode Characters -> Enable
