Hi 2253645a, 

Welcome to the community,

This does seem strange, as in most cases this would only occur when getting to the 3 or 4 SMS. However this may be a limitation of your network carrier, or it may be a limitation on a specific network mode, try changing the mode.

Menu > settings > More > Mobile Networks > Network mode > try WCDMA only or LTE preferred.

let us know how you get on.

I'm able to replicate this, you can use a third party app such as google messenger.

Just realised this thread is in the Z Ultra forum; mine is a Z1 Compact.

Should I re-post in the Z1 C forum?
