For example user could choose to limit technology usage to technologies like GSM and UMTS even if the LTE coverage would be available. Following value could be introduced to current API to enable this kind of selection: "gsm" Only GSM used for radio access. "umts" Only UMTS used for radio access. "gsm_umts" Only GSM or UMTS used for radio access. "lte" Only LTE used for radio access. Other approach could be that we would rephrase existing API so that = instead of using "only" LTE, we would use LTE whenever available and some older = technology when LTE coverage is lacking. So user would select "highest" allowed radio access without restrictions to use only one technology which has been = selected. This would save us from polluting value selection with options like = "gsm_umts", a decision we'd be grateful when we'll run oFono on 10G modems. ;) Use case for this could be energy conservation. At least I have habit to set network preference to 'GSM' to conserve battery life when I know I'm = going to travel places where 3G coverage is not that good or I'm not going to = need it.
