I did a quick test last night. Direct dial from my contacts did not work (never got the callback) with the two phones, a Moto V551 and V195, I tested it with. I had to dial manually via the sim menu. The old sim worked in these phone by direct dialing. I was really surprised it did not work in the V551 especially. All the callback sims I have used worked in this phone by dialing directly from the phone book.

I really could not tell if the callback was faster. It does not seem like it in my opinion.

Update: Direct dial from the phone contacts works on my MOto Q. Still no way to check credit balance from the phone, via sim menu or not. It does not work!

Likewise I can't check balance from handset (other than might be possible through refill IVR or customer service live operator short codes but I have no need to add credit right now). However, the website will let me see my balance, which does let me know the balance was transferred OK. Looks like they have a few bugs left to work out.
Note also the website has changed, and didn't allow me to see GSM rates on their calculator when I tried it yesterday.
Phonebook access isn't a big deal for me since I only dial a limited number of contacts and know the numbers by heart (home is #1, followed by office voicemail if I'm on a business trip).

Yackie not working in the US
 

At least for the past 4 days., the sim has not been able to connect to any network. Since it was not critical for me, I only emailed them yesterday just to make sure I am not the only one. Here is their response. May be others outside the US are experiencing the same thing.

Thank You for using our service. We are currently experiencing some technical difficulties with our service. Please bare with us as we are working diligently to resolve this issue in a timely manner.

Regards,

bare with us? Who's naked around here?

still didnt get the replacement card so i cant test. Honestly they finally lost my trust completely. This would be the 4th SIM-card and the 4th number for me. This is more a joke than a reliable service.

I received my replacement before christmas, just need to activate is. Number is still +354

It's a shame that they have a uk number but customer support is only available during USA est time from 9-6.

For a company promoting the card in europe, customer support should be open during european times.

The sim has bot been able to register on any networks here since about a week ago, as I posted above. May be things are okay on your end.

Just called them like it said in the letter to give my old number and new number.

They guy on the phone said he could not activate the new number because the system was down. Looks like it has been down for some time.

He will sent me a mail once he gets it up and running and my new card is activated.

In the mean time i'll wait for the mail and test the sim when it's activated.

Yackie is going through some issues.
 

Here is the last status I received from them today.
