Rivada alleged late last year it was wrongly excluded from bidding for a contract to build a $7 billion wholesale mobile phone network, a project known as Red Compartida.
The contract has been awarded to the only other bidder, a Mexican-US consortium known as Altan, which has denied any wrongdoing.
According to the Irish Times, Mexican officials have begun an examination of Rivada’s allegations.
Rivada will be expected to submit evidence to the inquiry of its allegations.
