We have no internet in our village or anywhere near so I tried all the companies in Silistra to see if they could help, but they all said no. Vivacom said there would be no signal hence it is unlikely a dongle will work. Mtel said I can buy a dongle for 30lev and try it out, if the mobile phone works than the dongle should too, but if it does not work I lose my 30lev. Friend had an Mtel dongle we tired it and it did no work. Global said more or less the same have to buy a dongle first. Anohter friend had a dongle we tried this out and it worked. It's fine for everyday use but not good for viewing videos etc, even if we got the highest dongle it would make no difference. I am very happy we have internet.
