Esatto, l'unica cosa 'certa' è che usare un cellulare che vede solo la banda 1900Mhz si avrà meno copertura che con uno che vede anche gli 850. E' la stessa cosa per chi viene in Europa vedendo solo una delle due frequenze GSM tra 900 e 1800.
Ripeto, al 99,99% chi ha curato quella pagina NON sapeva anche degli 850. Rogers imho non fa alcuna differenza di roaming, non ne ha il minimo interesse. Ne' 3 è in grado di bloccarsi solo sui 1900Mhz in quanto l'inibizione o viene dalla rete ospitante.... che pare non averne sul GSM come puoi controllare da solo: http://www.shoprogers.com/store/wire...erage/info.aspMa resta sempre il dubbio dell'accordo sulle frequenze che la 3 ha con Rogers...
Tra l'altro leggi qua cosa fa in piu' l'850... serve ANCHE in città a quanto pare
