SNS SMS intermittent failure on specific MNC in sweden (Telia, Tele2)

Hi

Since the 29th of september we've been receiving intermittent failures when sending sms. The content in sms are similiar and the api calls the same.

The only two mnc's that has failed is 1 and 7 in Sweden. We mostly send sms to carriers in Sweden. Tough mnc 1 and 7 (Telia and Tele2 respectively) stands for about half the amount of sms we send.

Example error:
{
"notification": {
"messageId": "35f21fc4-a893-5c45-8689-460f1f92be24",
"timestamp": "2021-09-27 12:10:41.446"
},
"delivery": {
"mnc": 1,
"numberOfMessageParts": 3,
"destination": "+4670...",
"priceInUSD": 0.21768,
"smsType": "Transactional",
"mcc": 240,
"providerResponse": "Unknown error attempting to reach phone",
"dwellTimeMs": 385,
"dwellTimeMsUntilDeviceAck": 3573
},
"status": "FAILURE"
}
