I have a Smart "Plug N' Talk" USB communication device which lets me call + text from a PC to any mobile or landline in the Philippines. It offers close to local call and text rates from as low as P6.50 / minute and P1.00 /SMS to the Philippines.
For around 19.50 GBP it comes with Smart SIM and P300 load. E-load prices are P300 for 5 GBP (valid up to 75 days), P500 for 8.50 GBP (valid up to 120 days) , and P1000 for 16 GBP (valid for up to 120 days).

The device wouldn't work on my new laptop, or a friend's laptop, after working previously on my netbook ( which "crashed" last week due probably to hard drive failing). Callingnow informed me the device could be corrupt, and offered to send a replacement for 5 GBP. This I received by first class post the next day (today). I simply removed my SIM, retaining the +069 number, and it now works perfectly. So I can still recommend the device, and the backup service offered should things go wrong.
