I had a BLU DASH JR with H2O and Redpocket (both ATT resellers with $100/yr
plans) until ATT dropped 2G. So I got a BLU R1 HD and only H2O worked when I
got it on Saturday. I called redpocket and they said to call Tuesday.
Today they got it to work. THen I realised H2O stopped working.
But they BOTH worked on the DASH JR. CLues?

Most "Dual SIM" phones are like that. The 2nd SIM only works on 2G,
only one SIM can connect to a modern network.

This doesn't refer to the question at hand, but I t hought my experience
over the last day would be worth posting (if not worth reading..

When the sim came in the mail it said that I shouldn't download data
until I get a data plan becuase it woudl be very expensive. I didnt'
get a data plan because.. could be wrong but I think I can get a much
better one when I get there.

So i was trying to turn off my data, but up until this morning, I'd
only found "turn off background data", not enough.

So yesterday and today I put in the new sim and tapped a couple things
settling on AT&T, at least I thought so, but when I got to the
notification line, a message went by that I have no ATT service!! And
instead of one white triangle (with the tall side at the right), I had
two triangles and they were both blank inside.

I went back and just for a test I made the new sim my main sim, and then
the message just said "no service", becuase it didn't know which service
the new sim was supposed to have.

So I made ATT the main sim again, by turning the second sim off with its
slide switch on the SIM page, and then I noticed Activities and calls
were set for ATT 012, SMS was set for ATT 01. bit cellular data was set
for the other sim!! So i set it to ATT, and I'll bet that covers all
the data. Then I went back to Settings/Data usage, where I
had tried to change it before, and it said "SIM off, to see the number,
first turn it on" Since I didn't want to turn on the new sim, I tapped
cancel and then it just returned to Settings.

So then I did turn on the second one, and I'm not getting a message
about no service... Well of course, because ATT is still working fine.
I have two triangles, one white and one empty. (Later I turned off the
second sim but I stil have two triangles.)

But I might be slowing something down or wasting battery to keep looking
for a signal for the second sim so I'll turn it off soon.

But the point was that the setting I wanted seems to be under SIM /
Activities / Cellular Data

BTW, for Cellular Data, I had to choose one, but for Calls and SMS,
there was a 3rd choice "Ask first". In my situation where one server
is in one country and the other in another, asking first doesn't make
sense, but some people have a need to split data and phone calls.
.....

It turns out I might even be able to buy the plan I'm thinking of right
at the airport.

(But I can leave the data on ATT (where it won't work), and that will I
suspect turn it off for the other one until I can buy the data plan.)

The big problem is IMO a) that there are no printed directiosn for some
phones (and the ones for my phone cover nothing but the obvious) and b)
it's not clear in advance what one can tap on and what one can't. It's
not like web browers that one can set to underline and display in
another color clickable links.
