Are you sure about this as I got this but when I went to top up , it only gives me data plans or some internation cash roaming plan , I called customer services and they said that this is a data only sim and and I need a voice sim for calls ?
I can confirm this works 100%. And just to say, you shouldn't have phoned Three about this. As this is something you shouldn't be doing as these are set by them as data sims, not phone sims. As in they don't want you to use them in your phones. But it works as the sims are identical to phone sims.
And to confirm again. Just this very second before posting I have done it again with my new phone (I bought a Moto E 2nd Gen for £35 from Vodaphone this week as it was on a mega deal for a 4G phone and chucked another data sim to use it as a backup phone).
But anyway there is two ways to top up. The first is by going to a supermarket and getting a phone voucher and typing it in via 444.
The second is by going to this web link:

I have just this second done this again with my new phone and put £2 on there. And made a call to my main phone to check it, and it worked perfectly making the call.
Do not phone Three!! They do not want you doing this. Before you get concerned worst case scenario is they can block this type of credit being added to the sim if you abuse it (and by abusing it I mean, telling them you have done this). For a punting phone, these are perfect. But I have been using one in my main phone for almost 2 months now and its been perfect.
