Creek wroteIn the end I went for Indosat 3.5G Broadband. It didn't work on Nusa Lembongan:icon_cry: It also didn't work West of Lovina. It did work in Ubud, where we spent some days.
It depends where, west of Lovina. Around Temukus, about 5 Km west of Central Lovina, it works fine. But in parts of Kaliasem, 1-2 Km west - there seems to be no 3G.
Also, I have found in many places where you cannot get 3G inside a house, you may get it from out on a verandah or Bale. If the modem can see a strong non-3G signal (4-5 bars) and a weaker 3G signal (1-2 bars), it seems to select the 3G - so it is worth trying a few different spots to see how your luck goes.
