If anyone has been following my other thread on the subject, they will know I am having very frustrating problems at the moment with my RBI connection. I would like to buy an unlocked Huawei B315s modem in good working order to make comparison tests. I would also be willing to 'rent' a device by paying an agreed price, then returning it later for a partial refund. I just need to find out whether the strange issues I am having are related to my modem or not. If you have something suitable, please reply with price.
