Using a Samsung Galaxy S7,
When someone send me a text message (sms), I often receive it several tens of minutes late, sometimes even a few hours late.
For instance:
Other: - We're going to the cinema tonight, wanna join?*
Other: - Come on join us!
Me: - Where?
*For instance I receive this message 1 hours later so this is kinda annoying.
I first suspected a contact failure of my sim card but it doesn't seem to me that this is the case
