SGSIII roams even when own network is selected manually

[Guest FoxVictor.be]

Hi All,

I'm a Belgian, working in the Netherlands, so I roam daily. To avoid costs, I select my own network manually. This worked fine for my ZTE OMC, running any flavour of tilal's custom roms.

However, on my SGSIII (i9300 Intl.), the phone insists to start roaming and selects a Dutch network, even though my own network was manually selected. This happened with the stock rom, as well as with CM10.1.

Does anyone else experience this? Known issues/reasons? Solutions?

Thanks. Gr, Filip
