Mobile prefixes
Landline prefixes
Prefix ranges still identify a line as mobile or fixed even where a number has been ported between operators, because the mobile and fixed blocks are separate and numbers do not move between them. Operator identification from a prefix, by contrast, stopped being reliable once portability arrived.
