XT vs Vodafone Global Roaming. One key difference.

By Steve Biddle, in , posted: 2-Jun-2009 06:48

NOTE: As of August 2010 Vodafone have upgraded their voicemail platform to allow the use of voicemail while roaming. They now offer the same features that Telecom do on XT.

See this post for more information: http://www.geekzone.co.nz/sbiddle/7366


One of the great features of GSM & UMTS networks is the ability to roam on foreign networks while travelling, and seamlessly use your mobile phone just as you would at home.

Pricing between both networks is similair in many respects but there is one key difference between both networks and that is the handling of voicemail support while roaming.

If somebody calls your phone you have two choices - answer the call or let the call divert to voicemail. Neither Vodafone or Telecom charge for voicemail deposits while you are inside New Zealand.

While you're roaming it's another story - due to the way roaming works if you do not answer your phone while roaming the call needs to establish a return path back to New Zealand and to the voicemail platform. This is where Vodafone and XT differ significantly.

If you're a Vodafone customer who's roaming call return to voicemail is not available on all networks.

On networks where it is not available the party calling you will receive a disconnected tone once you voicemail timeout is reached. They are not automatically diverted to your voicemail like they are in NZ and are unable to leave you a voicemail message, something many people find extremely annoying. On networks that do support a return path to the voicemail platform you ARE charged the normal inbound roaming rate of $1 per minute when people leave a message. If somebody leaves you a 3 minute voicemail message while you are roaming you're suddenly $3 out of pocket.

On Telecom XT a return path is available on all foreign networks while roaming and call return to voicemail is available on all networks. The mobile owner is also NOT charged for voicemail deposits left while you are roaming and a call is returned after the voicemail timeout period expires. This means there is no $3 bill when somebody leaves you a voicemail message.

If you're a regular roamer overseas and staying in contact is important then this significant difference may be of great importance to you and is something to factor in when deciding between mobile operators.

Makes very good sense. And what is the charge to return the call once listening to your voicemail?

Why doesn't Vodafone have this ability?

Why do you say that?

Vodafone Vodafone and Telecom XT have advantages and disadvantages. IMHO there is no "best" or "worst" network or company out of the two of them.

It's very interesting, though.  What about having your calls' diverted to a human being who takes your message and sends it to you via text?  Does that work overseas?  It would be cheaper, except for the fact that it's a premium service.  Telecom's Executive secretary gives you the choice of being put through to another number.  If you set it up, that is!  What about Vodafone?

Interesting. Do you have any examples of countries where Vodafone have no call return to voicemail ability? It's never happened to me.

Just been using the Telecom supplied XT mobile in Bangalore - works a treat. Nice to see the roaming is seamless on Telecom at last!
