I'm trying to make sure that if I import a phone to my country, it will likely work pretty much wherever I may go here. Most phones I'm looking at support every 4G band operated here, but I've noticed that on the GSM arena website, they will often give a list of supported bands for a given phone followed by a dash and a region name like 'Asia' or 'international' or 'USA'. One of the supported bands I'm looking at is operated in my country, but seems to be pretty rare, if I use that as a criterion the list of devices shrinks considerably as does the number of brands to choose from. One particular phone I looked at only lists support for the specific band I'm looking at in it's "-USA" list of supported bands. I'm confused by what this means for me, if that band is used in my country and I import a phone that only lists the band as supported in the US does that mean the phone wouldn't work here if I'm in an area where the only available tower operated on such a frequency? Why not? It sounds like it's physically capable.
The other question is, how do you assess the likelihood of this being a problem? The relative rarity of support for this band and the fact that it's only officially supported here, but seems only to have recently been licensed for people to build infrastructure operating on that band makes me think that there are likely very few towers actually using it here, but presumably more will eventually start to do so. My current phone has lasted me 6 years, almost 7 so I'll want to future-proof in this regard. In the time since I bought my last phone, carriers have abandoned any non VoLTE support so if the phone I bough then, hadn't had this compatibility it would have become a brick well ahead of its time so I'm weary of something like that happening.
EDIT: Something has occurred to me that didn't before and might answer my question, but then I guess it'd be good if anyone knew because this is only a guess on my part. Maybe the dash followed by region name is referring to model variants, as in, if you buy the US variant of the phone, then it supports these bands, and if you buy the international variant, it supports these bands etc etc. In that case, it would presumably mean that if I bought a variant model of a phone that lists support for a particular frequency band it should work anywhere in the world where those frequency bands are used not just the region mentioned after the list. I guess the trouble is that usually the sites I can find selling these phones to consumers in my market don't go in to anywhere near that level of detail so I'd have no way of knowing which model variant it was other than simply the manufacturer's marketing terms for their product lineup.
Yeh that definitely sucks they've rigged it up in a way that's unusual for this type of work and also forces you in to this situation. Redirecting is good and probably your best option, canny and sensitive people will notice you doing this and take it for the hint that it is but dense or uncaring people will probably carry on steering things in to places you don't want to go. If you're forced to eat with them then yes redirecting the conversation will work up to a point but it is a subtle skill to do so non-obviously. It's hard to advise specifically what to say like a script, though I would say if you just totally ignore the question altogether and switch topic very bluntly it's going to come across strange and prompt confusion and questioning. You'll need to somehow maintain the initial thread of their topic as lip service and then turn off down an unrelated avenue fairly smoothly. It's what politicians do professionally. Reading the other responses to your post I think they've got some really good ideas on how to deal with this if you really get forced in to conversing against your will. It's a subtle art of contributing basically nothing and rephrasing their same question back to them. I think another commenter suggested something along the lines of "I don't know much about that what about you?" and similarly bland and useless resonses. This is friendly enough not to piss anyone off and lame enough to be totally uninteresting which hopefully invites little follow up. If they continue on their original track, you can combine this with seguing to another topic.
I didn't suggest this to you initially because it doesn't sound like your natural style and I think advice is best if it allows the recipient to handle things mostly in their own way while helping to avoid pitfalls in doing so. I guess you'll have to navigate this daily frustration in a way a little outside of your comfort zone by carefully appearing to engage whilst really not and hopefully they'll find you so boring they don't bother anymore. Hopefully you don't mind this giving the impression that you're a boring person to the remaining 50% of your peers that don't bother you so much but sometimes it's a necessary evil.
