Orange gives gratis minutes exclusively for calling other Orange/Voo subscribers. Base does the same. So it would be useful to know before calling which network the other person is on – particularly if call credit is low.
Any tips on this?
In general, prefixes are relevant:
- 049× ← Orange
- 048× ← Base
- 047× ← Proximus
I forgot Proximus. But in any case, this is not reliable due to phone number portability whereby people swich carriers and keep their number. There are also prefixes that are not widely known (e.g. 0491).
The only way I know to check is to place a call then login after the fact and check whether gratis minutes were consumed or whether the balance dropped. Is there a way to check a number without contacting it?
