Tab S10+ update frequency

[Samsung_chwPx9R]

I recently saw that One UI8 was released to the tab s10+.  I checked to see if I received it, and have not.  I noticed that I haven't had a security update since March 1, 2025.  I have SM-X828U/DS.

I cleaned Cache, and connected to Smart Switch.  No updates are showing.

I understand that One Ui8 may not be available to me yet, but shouldn't there be security updates every 3 months?

Yes, tabs are supposed to receive quarterly updates. I notice your model number indicates dual SIM. Do you currently have a SIM installed?
