Free international calling with

A new service from Lightup Network Solutions: allows free or cheap calling to 160 countries worldwide

Frankfurt am Main, 12th March 2012 – Everyone who frequently calls abroad knows that such a call can become quickly quite expensive. remedies that situation: users that hold an unlimited or included minutes plans for German landlines or mobiles are now able to call abroad completely free of charge or at the price of a regular local or mobile call.

„Everyone who's in charge of an unlimited or included minutes plan can now call to more than 70 countries free of charge through our landline and mobile access numbers", explains Markus Stalder, CEO of Lightup Network Solutions GmbH & Co. KG and And for users that don't have an included minutes plan just the normal fee for a regular landline or mobile call applies.

Besides the two landline and mobile access numbers offers also two premium access numbers (01803 and 01805) which are not free but get charged at 9 or 14 Cents per minute (up to 42 Cents per minute when calling from a mobile), and through these numbers additional 90 countries can be reached.

Using is extremely easy: neither a registration, contract nor software is required. Just call one of the 4 access numbers, type in the number of the callee abroad, and you're connected - free or at a very low rate.

Worldwide, modern, low-cost and privacy-protected telephony with

Lightup Network Solutions provides virtual telephone numbers in 63 countries to residential and business customers

Frankfurt am Main, 21st December 2011 – Calling abroad or calling back home is usually quite expensive - but by utilizing an own virtual telephone number in the country where family, friends, business partners or customers are at home, telephone costs can now get reduced dramatically. Since December 2011 Lightup Network Solutions provides, under the label, a novel telecommunications solution to consumers and SMBs, that, besides a virtual presence in more than 60 countries, also allows extremely cheap international calling.

„Especially businesses can now easily create a worldwide presence and increase their global reach", explains Markus Stalder, CEO of Lightup Network Solutions GmbH & Co. KG and „The incentive for customers abroad to call a foreign business at the price of a local call should not be underestimated."

Through an online self-service portal the customer can comfortably and instantly set where incoming calls should get forwarded to: Skype, Google Talk, a Voice-over-IP provider of choice, a regular landline or mobile phone anywhere in the world or to a custom SIP-, H.323- or IAX-destination. Existing telecommunications hardware as well as the existing telephony providers need not to get changed; the web-based customer portal can be used intuitively.

Further advantages of an own virtual telephone number:
- Privacy: Whenever there's a need to publish your own telephone number, globalnumbers' virtual telephone numbers protect your privacy
- Eliminate all roaming fees when travelling abroad
