My daughter ported to Kogan from Skinny recently and has nothing but problems since.
She has a OnePlus 6T, has switched the sims, set the call, sms and data defaults to the Kogan sim and has updated both the data and sms APN's.
The issue now is she only appears to receive SMS from people on VF. I can text her with my Kogan sim, but not my Skinny sim. Same with two of her friends, one who is on VF one on Spark.
Is there something else she should be setting up or checking ?
