See what our customer have to say about Teloz
By obtaining a virtual phone number with a 510 area code forwarded to my cell, my small boutique has established a local feel without costly hardware. Customers light up seeing a 510 number, leading to warm conversations that go beyond transactions. This simple virtual number has made my business part of the local community.
As an independent consultant based in India with clients worldwide, My 510 number gives my Upstate New York clients a local call experience, strengthening our relationships. Similarly, my New York 212 number has allowed me to better serve my Northeast US clients. And for my UK clients, my London 020 number has been crucial for establishing legitimacy. All this without needing physical offices in any of those regions. The local presence conveyed by these numbers has been key for growing my business internationally.
The advanced features like call recording, conferencing, and call handling have streamlined operations. I can now record calls with my team and share for training instead of repeating myself. The call forwarding lets me toggle between office and mobile seamlessly. And the conference calling bridges global team discussions. The capabilities and cost savings have been an absolute game changer compared to traditional telephony. These virtual numbers have opened my eyes to how a small business can efficiently compete on a global scale.
As an international sales rep, the flexibility of virtual phone numbers has been invaluable. I can instantly get local numbers when entering new markets to test demand, then easily cancel them if the market doesn't pan out. This agility to adjust my phone presence when pivoting between countries has saved tons of time and money compared to traditional telephony. The quick deployment and cancellation of virtual numbers has been a game-changer for optimizing my global sales.
