Can’t make calls when had further roaming add on in the US

[Jill52]

Why can’t I make calls in the US when I’ve had  an add on further roaming add on 

[bristolian]

The Roam Further pass is just a billing add-on, it doesn't enable the international roaming facility. It is this which enables your phone to connect to foreign networks, which in turn allows you to make & receive calls & texts over that mobile network connection.

Did you enable roaming by texting ROAMING to 150 before leaving the UK?

[Jill52]

I did text roaming to 150 , how do you think I’ve got the data and texts

You never said you can get data & send texts.

[chistery]

What phone do you have and which network are you roaming on?

[Jill52]

I’m in the states at the moment , had further roaming add on and I can’t make phone calls or text , can only contact others in my party  using WhatsApp and iMessage via my data . 

Returning home now so have been 9 days without being able to call or text anyone 

[Jill52]

Yes it’s all been turned on 

[Jill52]

Of course I activated  my roaming and went into my online account  to do everything 

[XRaySpeX]

@Jill52 : Of course? You cannot currently activate roaming via your online a/c. It has to be done by texting ROAMING to 150 while in UK or by calling CS.

[Jill52]

Of course I did  , I’m not stupid , when I arrive in the US even had a text message to say  welcome and saying with the go further add on I could make calls and texts in the untitled states , but absolutely nothing other than using my data , to contact the people I’m with here in America . 
Everything turned on before coming here
