Republic has no business presence in Alaska, Hawaii or New Hampshire and consequently doesn’t ship to those locations. Please see the FAQs here: My Republic Service. Quoting:
Is service available in the Virgin Islands, Puerto Rico, Alaska, New Hampshire or Hawaii?
You can make outbound calls to Per Call Countries. Per Call Countries include Puerto Rico, Guam, US Virgin Islands, American Somoa, Northern Mariana Islands, Johnston Atoll, Midway Atoll, and the Wake Island. Service is not available in Alaska, New Hampshire, or Hawaii.
The above said, it’s possible to obtain an appropriate Republic SIM. If your daughter purchased a Republic 3.0 phone from an eBay seller, Amazon will ship to Hawaii: Republic Wireless SIM Starter Kit. If she purchased a legacy Republic phone, please raise a help ticket, so that Republic may provide the needed SIM free of charge.
Regarding Hawaii phone numbers, the following may help provide context:
Republic, like all service providers, relies on a Local Exchange Carrier (LEC) to host phone numbers. LEC is telephone industry jargon for phone company. Republic uses Bandwidth.com, as its’ LEC. Use of Bandwidth is part of Republic’s blended WiFi/cell service. Bandwidth needs to have “presence” in the rate center where the number you wish to obtain or transfer (port) is located. A rate center is a geographic area, usually but not always a city or town. The rate center your number is located in is determined by the area code and prefix (first six digits) of your phone number. No carrier has presence in every rate center. Bandwidth has presence in most but not all rate centers. Unfortunately, if Bandwidth does not have rate center presence you will not be able to obtain or transfer a number. To the best of my knowledge, Bandwidth has no presence in any Hawaiian rate centers.
An analogy that might help make sense of this. I grew up in Massachusetts where Papa Gino’s is a popular place to get pizza. Now that I’m in Florida as much as I’d like to purchase a Papa Gino’s pizza, I’m unable to do so because they have no restaurants (presence) here.
