I haven't been outside of the US much since early 2020, but I have taken two trips, one to Aruba in May 2021 and one to the UK in September 2021. I noticed that for the bill in May that there wasn't any indication of roaming even though I definitely did roam on local networks in Aruba. Mrs. Majuki's line does show the line items of Service: Web Access with Origin: San Francisco (Aruba) and Type: R. For the same dates mine shows "Mobile Internet" even though we roamed the same dates. I did not have a data pass, and any data pass will show something like Service: International Roaming Data Passes, Origin: San Francisco (China (China Mobile)), and Type: R. We both received the welcome text upon arrival.

I was in the UK by myself, and I got the expected line items showing roaming: Service: Web Access, Origin: United Kingdom, and Type: R.

Does anyone have an idea what caused the discrepancy?
