SMS message doesn't get sent out/received

[raresn]

Hey guys! I am having quite a big problem here and we are hoping for some help:

• we send out an sms to a phone number, it appears inside Messaging (Android phone), but the client does not receive it.
• tried twice, both messages, same result.
• Manually copied the text from Messaging and pasted it again, hit sent - message delivered and received by client. Tries on two phones, doesn't have anything to do with the phone. Around 20% of the messages sent out have this problem and we don't know what to do. We are more than happy to test any debug versions you can spare.

Can you show the code you are using to send the SMS and some details on the devices you have encountered this issue with?

The sending is handled by the OS so not really sure what could be happening, unless the content is potentially invalid (too long / invalid characters?).

We are having delivery issues as we told you. Most messages are being delivered eventually, but some with delays up to 12 hours or more. We figured we didn’t log delivery reports that we received so late, but now we do and in the last 24h we noticed some delivery reports arrive 12 hours late or more. We have delays of 1 hour or more on about 50% of the messages sent. For today only most delayed messages get delivered in about 2.5 hours. Need to reduce this to 1 hour or less. We send reminders and some are 2 hours before event starts, sending message after the event started is pointless and bad business for us. Right now we are using the latest ANE files, tested with an Samsung Galaxy S4 and Xiaomi Redme 6 The texts are for sure short enough (<160 chars), and no special characters.

Delivery issues like that sound like a carrier related issue. Can't see how the ANE would be causing this, we simply construct the SMS and pass it to the system to handle.
