The interceptions have been used to target drug traffickers and alien smugglers, "a far cry" from terrorists with weapons of mass destruction. See this slide.

Intercept says:

One memo indicates that SOMALGET data is covertly acquired under the auspices of “lawful intercepts” made through Drug Enforcement Administration “accesses”– legal wiretaps of foreign phone networks that the DEA requests as part of international law enforcement cooperation.

When U.S. drug agents need to tap a phone of a suspected drug kingpin in another country, they call up their counterparts and ask them set up an intercept. To facilitate those taps, many nations – including the Bahamas – have hired contractors who install and maintain so-called lawful intercept equipment on their telecommunications. With SOMALGET, it appears that the NSA has used the access those contractors developed to secretly mine the country’s entire phone system for “signals intelligence” –recording every mobile call in the country.

The DEA has morphed from a drug agency into an agency of Global Holy Warriors.

“DEA is actually one of the biggest spy operations there is,” says Finn Selander, a former DEA special agent who works with the drug-reform advocacy group Law Enforcement Against Prohibition. “Our mandate is not just drugs. We collect intelligence.”
