I suggest aggregating the experiences and solutions and propose the following format:
“Land”, “Home/Roaming”
- “Provider”, “OS Version”, “Model”: Solution → Speed
Please put “?” in front if unsure, and “?” if unknown.
Spain, Roaming:
- ?Movistar, ?v4.0.1, Xperia 10: no problems → ?/?
Switzerland, Home:
- Salt, v4.4,0.72, Xperia 10 III: Remove SIM Card PIN → LTE 150/45
- Salt, v4.4,0.72, Xperia 10 II: no problems → LTE 150/45
