CAT and TOT agree on HSPA roaming

31 May 2011

Thai sister telcos TOT and CAT Telecom have agreed in principle to allow each others’ customers to roam on the 3G W-CDMA/HSPA networks that the state-owned pair are currently building out, CAT via its partnership with True Move to roll out 850MHz services across Bangkok and other areas, and TOT through its recent contract to expand its 2100MHz services beyond the capital into provincial cities. The companies aim to sign a memorandum of understanding (MoU) covering voice and data roaming services in the near future, local newspaper The Nation reports. CAT’s CEO Jirayuth Rungsrithong was quoted as saying that the two HSPA networks will complement each other as TOT’s 2100MHz spectrum was ideal for covering densely populated major cities, while CAT’s 850MHz frequencies were well suited to cover wider, more sparsely populated areas in the provinces.

TOT also revealed that it is in talks with cellco Advanced Info Service (AIS) to expand a roaming agreement under which a current maximum of 50,000 TOT 3G users are permitted to roam on AIS’ nationwide GSM mobile voice network.
