Yim Siam Telecom operates a quality network; deploys the latest technologies; sends most of its traffic via BT’s international network and is located in the most liberal telecom market in the world (UK). The combination of these factors enables us to provide our customers with a low-cost, high-quality international calling service.

Yim Siam Telecom is authorised to provide communications services in exactly the same way as British Telecom. We operate our network under the General Authorisation conditions of the EC Authorisation Directive (Directive 2002/20/EC).

Yim Siam Telecom has been in business for 7 years and has offices in Thailand and UK. We are 100% owned by our Thai parent company (Euro Thai Exchange Process Company Ltd.), which has its main office in Klongton Nua, Wattana, Bangkok. We are the first Thai Telecommunications Company ever to provide services in the UK.

Yim Siam Telecom’s services are specifically focused on the Thai community in UK and tailored to meet their needs, so you don’t have to suffer the exorbitant prices charged by British Telecom and UK Mobile Operators to make international calls. Of course, anyone in UK can use the Yim Siam service.

We also provide other more specialist services for businesses. For more information, simply click on 'Future Services' or send an email to: enquiries@yimsiam.biz with your address details and an information pack to be sent to you.

We don’t aim to please our customers – we aim to delight them - and we work really hard at making the 'Yim Siam experience' something all our customers will really enjoy and will tell their friends about.
