UM+ sim and caller recognition

[prion]

I am using the UM plus sim and have noticed that when someone calls you, you can not see his number. I was wondering if others have also noticed this. This used to happen with mannx sims in the past.

Hi,

with international cards it a Roulette Game if you see his number or he will see your number. This depends on the low low low cost routing of the involved carriers and is not trivial.

Obviously if a calling card is used caller ID will not be passed. But, if someone calls me direct on it, the callerId shows up most of the time. Also, when I used it last year by forwarding to it via voicestick, the caller's ID showed up on pretty much every call.

I forgot to mention that this issue happens with every route I have tried: Both low cost as well as normal telephone network.
For example this does not happen when I call normal UM or an estonian sim

Me too i've the same problem with all sim cards. But this problem only since some months

I've some problems with my um+. Yesterday i've tried to call 3 of my national sim: calls leave ok, but my national sim (wind,vodafone) don't receive the calling.
Have you the same problem?

I had the same problem. First I that that betamax had a problem because it was difficult to reacht the um+ number. On the other hand when calling using my normal cellphone, no problems. But for both, no caller id on different networks.

today now problem and everything works.

I am still having the same issue. No caller id is shown on all calls.

[fedeprovenza]

Caller id doesn't appear on different networks

I've bought a new um+, today i've got it. It works without problems!
